The contagious impact of playing violent video games on aggression: Longitudinal evidence

Tobias greitemeyer.

1 Department of Psychology, University of Innsbruck, Innsbruck Austria

Meta‐analyses have shown that violent video game play increases aggression in the player. The present research suggests that violent video game play also affects individuals with whom the player is connected. A longitudinal study ( N  = 980) asked participants to report on their amount of violent video game play and level of aggression as well as how they perceive their friends and examined the association between the participant's aggression and their friends’ amount of violent video game play. As hypothesized, friends’ amount of violent video game play at Time 1 was associated with the participant's aggression at Time 2 even when controlling for the impact of the participant's aggression at Time 1. Mediation analyses showed that friends’ aggression at Time 1 accounted for the impact of friends’ amount of violent video game play at Time 1 on the participant's aggression at Time 2. These findings suggest that increased aggression in video game players has an impact on the player's social network.

1. INTRODUCTION

Given its widespread use, the public and psychologists alike are concerned about the impact of violent video game play. In fact, a great number of studies have addressed the effects of exposure to violent video games (where the main goal is to harm other game characters) on aggression and aggression‐related variables. Meta‐analyses have shown that playing violent video games is associated with increased aggression in the player (Anderson et al., 2010 ; Greitemeyer & Mügge, 2014 ). The present longitudinal study examines the idea that violent video game play also affects the player's social network, suggesting that concern about the harmful effects of playing violent video games on a societal level is even more warranted.

1.1. Theoretical perspective

When explaining the effects of playing violent video games, researchers often refer to the General Aggression Model (GAM) proposed by Anderson & Bushman ( 2002 ). According to this theoretical model, person and situation variables (sometimes interactively) may affect a person's internal state, consisting of cognition, affect, and arousal. This internal state then affects how events are perceived and interpreted. Based on this decision process, the person behaves more or less aggressively in a social encounter. For example, playing violent video games is assumed to increase aggressive cognition and affect, which in turn results in behavioral aggression. An extension of this model further assumes that increased aggression due to previous violent video game play may instigate an aggression escalation cycle in that the victim also behaves aggressively (cf. Anderson & Bushman, 2018 , Figure 5). The present research tested key predictions derived from the GAM and its extension, that (a) violent video game play is associated with increased aggression in the player and that (b) individuals who are connected to the player will also become more aggressive.

1.2. Effects of violent video game play on aggression

The relationship between violent video game play and aggression has been examined in studies employing cross‐sectional, longitudinal, and experimental designs. Cross‐sectional correlational studies typically show a positive relationship between the amount of violent video game play and aggression in real‐world contexts (e.g., Gentile, Lynch, Linder, & Walsh, 2004 ; Krahé & Möller, 2004 ). Several longitudinal studies have been conducted, showing that habitual violent video game play predicts later aggression even after controlling for initial aggressiveness (e.g., Anderson, Buckley, & Carnagey, 2008 ). That violent video game play has a causal impact on aggression and related information processing has been demonstrated by experimental work (e.g., Anderson & Carnagey, 2009 ; Gabbiadini & Riva, 2018 ). Finally, meta‐analyses corroborated that violent video game play significantly increases aggressive thoughts, hostile affect, and aggressive behavior (Anderson et al., 2010 ; Greitemeyer & Mügge, 2014 ). Some studies failed to find significant effects (e.g., McCarthy, Coley, Wagner, Zengel, & Basham, 2016 ). However, given that the typical effect of violent video games on aggression is not large, it is to be expected that not all studies reveal significant effects.

1.3. The contagious effects of aggression

Abundant evidence has been collected that aggression and violence can be contagious (Dishion, & Tipsord, 2011 ; Huesmann, 2012 ; Jung, Busching, & Krahé, 2019 ). Indeed, the best predictor of (retaliatory) aggression is arguably previous violent victimization (Anderson et al., 2008 ; Goldstein, Davis, & Herman, 1975 ). However, even the observation of violence can lead to increased violence in the future (Widom, 1989 ). Overall, it is a well‐known finding that aggression begets further aggression. Given that violent video game play increases aggression, it thus may well be that this increased aggression then has an impact on people with whom the player is connected.

Correlational research provides initial evidence for the idea that the level of people's aggression is indeed associated with how often their friends play violent video games (Greitemeyer, 2018 ). In particular, participants who did not play violent video games were more aggressive the more their friends played violent video games. However, due to the cross‐sectional design, no conclusions about the direction of the effect are possible. It may be that violent video game players influence their friends (social influence), but it is also conceivable that similar people attract each other (homophily) or that there is some shared environmental factor that influences the behavior of both the players and their friends (confounding). That is, it is unclear whether indeed aggression due to playing violent video games spreads or whether the effect is reversed, such that aggressive people are prone to befriend others who are attracted to violent video game play. Moreover, it is possible that some third variable affected both, participants’ reported aggression and their friends’ amount of violent video game play. There is also the possibility that people are unsure about the extent to which their friends play violent video games. In this case, they may perceive their friends as behaving aggressively and then (wrongly) infer that the friends play violent video games. To disentangle these possibilities and to show that the effect of violent video game play (i.e., increased aggression in the player) indeed has an impact on the player's social network, relationships among variables have to be assessed over time while covarying prior aggression (Bond & Bushman, 2017 ; Christakis & Fowler, 2013 ).

Verheijen, Burk, Stoltz, van den Berg, and Cillessen ( 2018 ) tested the idea that players of violent video games have a long‐term impact on their social network. These authors found that participants’ exposure to violent video games increased their friend's aggressive behavior 1 year later. However, given that the authors did not examine whether the violent video game player's increased aggression accounts for the impact on their friend's aggressive behavior, it is unknown whether violent video game play indeed instigates an aggression cycle. For example, players of violent video games may influence their friends so that these friends will also play violent video games. Any increases in aggression could then be an effect of the friends playing violent video games on their own.

1.4. The present research

The present study examines the longitudinal association between the participant's aggression and their friends’ amount of violent video game play, employing an egocentric networking approach (Stark & Krosnick, 2017 ). In egocentric networking analyses, participants provide self‐reports but also report on how they perceive their friends. In the following, and in line with Greitemeyer ( 2018 ), the friends were treated as the players and the participant was treated as their friends’ social network. Please note that ties between the participant's friends (i.e., whether friends also know each other) were not assessed (Greitemeyer, 2018 ; Mötteli & Dohle, 2019 ), because this information was not needed for testing the hypothesis that participants become more aggressive if their friends play violent video games. It was expected that friends’ amount of violent video game play at Time 1 would predict the participant's aggression at Time 2 even when controlling for the impact of the participant's aggression and amount of violent video game play at Time 1. It was further examined whether friends’ aggression at Time 1 would account for the impact of friends’ amount of violent video game play at Time 1 on the participant's aggression at Time 2. Such findings would provide suggestive evidence that violent video game play may instigate an aggression cycle. The study received ethical approval from the Internal Review Board for Ethical Questions by the Scientific Ethical Committee of the University of Innsbruck. The data and materials are openly accessible at https://osf.io/jp8ew/ .

2.1. Participants

Participants were citizens of the U.S. who took part on Amazon Mechanical Turk. Because it was unknown how many of the participants will complete both questionnaires, no power analyses were conducted a priori but a large number of participants was run. At Time 1, there were 2,502 participants (1,376 females, 1,126 males; mean age = 35.7 years, SD =  11.8). Of these, 980 participants (522 females, 458 males; mean age = 38.9 years, SD =  12.5) completed the questionnaire at Time 2. Time 1 and Time 2 were 6 months apart. There were no data exclusions, and all participants were run before any analyses were performed. The questionnaire included some further questions (e.g., participant's perceived deprivation) that are not relevant for the present purpose and are reported elsewhere (Greitemeyer & Sagioglou, 2018 ). 1 Given that the questionnaire was relatively short, no attention checks were employed.

2.2. Procedure and measures

Procedure and measures were very similar to Greitemeyer ( 2018 ), with the main difference that individuals participated at two time points (instead of one). After providing demographics, self‐reported aggressive behavior was assessed. As in previous research (e.g., Krahé & Möller, 2010 ), participants indicated for 10 items how often they had shown the respective behavior in the past 6 months. Sample items are: “I have pushed another person” and “I have spread gossip about people I don't like” (5 items each address physical aggression and relational aggression, respectively). All items were rated on a scale from 1 ( never ) to 5 ( very often ), and scores were averaged. Participants were then asked about their amount of violent video game play, employing one item: “How often do you play violent video games (where the goal is to harm other game characters)?” (1 =  never to 7 =  very often ).

Afterwards, participants learned that they will be asked questions about people they feel closest to. These may be friends, coworkers, neighbors, relatives. They should answer questions for three contacts with whom they talked about important matters in the last few months. For each friend, they reported the level of aggression (αs between = 0.90 and 0.91) and the amount of violent video game play, employing the same questions as for themselves. Responses to the three friends were then averaged. Finally, participants were thanked and asked what they thought this experiment was trying to study, but none noted the hypothesis that their friend's amount of violent video game play would affect their own level of aggression. At Time 2, the same questions were employed. Reliabilities for how participants perceived the level of aggression for each friend were between 0.89 and 0.90.

Descriptive statistics, intercorrelations, and internal consistencies of all measures are shown in Table ​ Table1 1 .

Note : For Time 1, N  = 2,502; for Time 2, N  = 980. All correlation coefficients: p  < .001. Where applicable, α reliabilities are presented along the diagonal.

3.1. Time 1 ( N  = 2,502)

The relationship between the amount of violent video game play and reported aggression was significant, both for the participant and the friends. That is, violent video game play was associated with increased aggression in the player and participants perceived their friends who play more violent video games to be more aggressive than their less‐playing friends. Participant's and friends’ amount of violent video game play as well as their level of reported aggression, respectively, were also positively associated, indicating that participants perceived their friends to be similar to them. Most importantly, participant's aggression was significantly associated with friends’ amount of violent video game play. 2

It was then examined whether friends’ amount of violent video game play is still associated with the participant's aggression when controlling for the participant's amount of violent video game play. Participant sex (coded 1 = male, 2 = female) and age were included as covariates. In fact, a bootstrapping analysis showed that the impact of friends’ amount of violent video game play remained significant (point estimate = 0.08, SE  = 0.02, t  = 4.72, p  < .001, 95% confidence interval [CI] = [0.05, 0.11]). Participant's amount of violent video game play (point estimate = 0.03, SE  = 0.01, t  = 2.18, p  = .029, 95% CI = [0.00, 0.05]) and the interaction were also significant (point estimate = −0.01, SE  = 0.00, t  = 2.41, p  = .016, 95% CI = [−0.02, −0.00]). At low levels of the participant's amount of violent video game play (− 1 SD, equals that the participant does not play violent video games in the present data set), friends’ amount of violent video game play was associated with the participant's aggression (point estimate = 0.07, SE  = 0.01, t  = 5.06, p  < .001, 95% CI = [0.04, 0.10]). At high levels of the participant's amount of violent video game play ( + 1 SD), friends’ amount of violent video game play was also associated with the participant's aggression (point estimate = 0.03, SE  = 0.01, t  = 3.14, p  = .002, 95% CI = [0.01, 0.06]), but the effect was less pronounced. Participants were thus most strongly affected by whether their social network plays violent video games when they do not play violent video games themselves (Figure ​ (Figure1). 1 ). Participant sex was not significantly associated with the participant's aggression (point estimate = −0.04, SE  = 0.02, t  = 1.95, p  = .052, 95% CI = [−0.09, 0.00]), whereas age was (point estimate = −0.01, SE  = 0.00, t  = 7.84, p  < .001, 95% CI = [−0.009, −0.005]).

3.2. Time 1 and Time 2 ( N  = 980)

To examine the impact of friends’ amount of violent video game play on the participant's aggression over time, a cross‐lagged regression analysis was performed on the data. Participant's amount of violent video game play, friends’ amount of violent video game play, participant's aggression at Time 1, as well as participant sex and age were used as predictors for participant's aggression at Time 2. The overall regression was significant, F (5,974) = 68.92, R 2  = 0.26, p  < .001. Most importantly, friends’ amount of violent video game play at Time 1 significantly predicted participant's aggression at Time 2, t  = 2.60, β  = .09, 95% CI = (0.02, 0.16), p  = .009. Participant's aggression showed high stability, t  = 16.77, β  = .48, 95% CI = (0.42, 0.53), p  < .001, whereas the participant's amount of violent video game play at Time 1 did not significantly predict the participant's aggression at Time 2, t  = 1.77, β  = −.07, 95% CI = (− 0.14, 0.01), p  = .077 (Figure ​ (Figure2 2 ). 3 , 4 Participant sex also received a significant regression weight, t  = 2.08, β  = −.06, 95% CI = (−0.12, −0.00), p  = .038, whereas age did not, t  = 1.93, β  = −.06, 95% CI = (−0.12, 0.00), p  = .054. The reverse effect that the participant's aggression at Time 1 predicts their friends’ amount of violent video game play at Time 2 when controlling for the participant's amount of violent video game play and friends’ amount of violent video game play at Time 1, as well as participant sex and age, was not significant, t  = 0.67, β  = .02, 95% CI = (−0.03, 0.06), p  = .504.

Participant's aggression at Time 2 simultaneously predicted by friends’ amount of violent video game play, participant's aggression, and participant's amount of violent video game play at Time 1. Participant sex and age were controlled for, but were not included in the figure (see the main text for the impact of participant sex and age). * p  < .01, ** p  < .001 ( N  = 980)

Finally, it was examined whether the impact of friends’ amount of violent video game play at Time 1 on the participant's aggression at Time 2 would be mediated by friends’ level of aggression at Time 1 (while controlling for the participant's aggression and amount of violent video game play at Time 1 as well as participant sex and age). A bootstrapping analysis (with 5.000 iterations) showed that the impact of friends’ level of aggression at Time 1 on the participant's aggression at Time 2 was significant (point estimate = 0.16, SE  = 0.04, t  = 4.28, p  < .001, 95% CI = [0.09, 0.23]). Participant's aggression at Time 1 was also a significant predictor (point estimate = 0.34, SE  = 0.03, t  = 10.19, p  < .001, 95% CI = [0.27, 0.40]). Friends’ amount of violent video game play at Time 1 (point estimate = 0.03, SE  = 0.01, t  = 1.82, p  = .069, 95% CI = [−0.00, 0.05]) and participant's amount of violent video game play at Time 1 (point estimate = −0.01, SE  = 0.01, t  = 1.65, p  = .099, 95% CI = [−0.03, 0.00]) were not significant predictors. Participant sex significantly predicted the participant's aggression at Time 2 (point estimate = −0.06, SE  = 0.03, t  = 2.31, p  = .021, 95% CI = [−0.11, −0.01]), whereas age did not (point estimate = −0.00, SE  = 0.00, t  = 1.90, p  = .058, 95% CI = [−0.00, 0.00]). The indirect effect was significantly different from zero (point estimate = 0.01, 95% CI = [.00, 0.02]), suggesting that participants are more aggressive if their friends play violent video games for the reason that these friends are more aggressive. Figure ​ Figure3 3 displays a simplified version of this mediation effect, based on regression coefficients and without controlling for the participant's aggression at Time 1, the participant's amount of violent video game play at Time 1, participant sex, and age.

4. DISCUSSION

Violent video games have an impact on the player's aggression (Anderson et al., 2010 ; Greitemeyer & Mügge, 2014 ), but—as the present study shows—they also increase aggression in the player's social network. In particular, participants who do not play violent video games reported to be more aggressive the more their friends play violent video games. Mediation analyses showed that the increased aggression in the friends accounted for the relationship between friends’ amount of violent video game play and the participant's aggression. Because changes in aggression over time were assessed, the present study provides evidence for the hypothesized effect that violent video game play is associated with increased aggression in the player, which then instigates aggression in their social network. Importantly, the impact of the participant's amount of violent video game play was controlled for, indicating that the relationship between friends’ amount of violent video game play and the participant's aggression is not due to the friends being similar to the participants. Moreover, the reverse effect that aggressive people will become attracted to others who play violent video games was not reliable. The present research thus documents the directional effects that violent video games is associated with increased aggression in the player and that this increased aggression then has an impact on people with whom the player is connected.

Overall, the present study provides comprehensive support for key hypotheses derived from the GAM and its extension (Anderson & Bushman, 2018 ). It shows that violent video game play is associated with increased aggression in the player and it documents that others who are connected to players might be also affected even when controlling for their own amount of violent video game play. To the best of my knowledge, this study is the first that shows that because violent video game players are more aggressive their friends will become aggressive, too. Previous research either employed a cross‐sectional design and thus could not address the direction of the effect (Greitemeyer, 2018 ) or did not examine whether the effect of violent video game play (i.e., increased aggression) indeed spreads (Verheijen et al., 2018 ). As proposed by the GAM and its extension (Anderson & Bushman, 2018 ), increased aggression in violent video game players appears to instigate an aggression escalation cycle (cf. Anderson et al., 2008 ).

It is noteworthy, however, that the longitudinal effect of the participant's amount of violent video game play at Time 1 on the participant's aggression at Time 2 was not reliable. Hence, although there were significant correlations between participants’ aggression and their violent video game use at both time points, the present study does not show that repeatedly playing violent video games leads to long‐term changes in aggression. However, a recent meta‐analysis of the long‐term effects of playing violent video games confirmed that violent video game play does increase physical aggression over time (Prescott, Sargent, & Hull, 2018 ), although the effect size was relatively small ( β  = 0.11) and thus single studies that produce nonsignificant results are to be expected. Importantly, in the present study, a single‐item measure of violent video game play was employed. In contrast, previous research on the relationship between violent video game play and the player's aggression has often employed multi‐item measurement scales that are typically more reliable and precise (for an overview, Busching et al., 2015 ). Hence, it may well be that due to the limitations of the single‐item measure of the participant's amount of violent video game play the relationship between participants’ violent game play and their aggressive behavior was artificially reduced.

Even though the longitudinal design allows ruling out a host of alternative explanations for the impact of violent video games on the player's social network, causality can only inferred by using an experimental design. Future research may thus randomly assign participants to play a violent or nonviolent video game (players) and assesses their aggression against new participants (partners). It can be expected that the partners suffer more aggression when the player had played a violent, compared to a nonviolent, video game. Afterwards, it could be tested whether the partner of a violent video game player is more aggressive than a partner of a nonviolent video game player. Given that the partner is not exposed to any video games, firm causal conclusions could be drawn that violent video game play affects aggression in people who are connected to violent video game players. It could be also tested whether the partner of a violent video game player would not only be more likely to retaliate against the player, but also against a third party. In fact, previous research into displaced aggression has shown that people may react aggressively against a target that is innocent of any wrongdoing after they have been provoked by another person (Marcus‐Newhall, Pedersen, Carlson, & Miller, 2000 ). It may thus well be that the effect of playing violent video games spreads in social networks and that even people who are only indirectly linked to violent video game players are affected.

An important limitation of the present egocentric network data is the reliance on the participant's perception of their social network, leaving the possibility that participants did not accurately perceive their friends. It is noteworthy that participants perceived their friends to be highly similar to them. In this regard, it is important to keep in mind that participants always provided self‐ratings first, followed by perceptions of their friends. It is thus conceivable that participants used their self‐ratings as anchors for the perceptions of their friends. Such a tendency, however, would reduce the unique effect of friends’ amount of violent video game play on the participant's aggression when controlling for the participant's amount of violent video game play. The finding that participants in particular who do not play violent video games reported to be more aggressive if their friends play violent video games also suggests that the impact of violent video games on the player's social network is not due to participants providing both self‐reports and how they perceive their friends. Finally, rather than by their friends’ objective qualities, people's behavior should be more likely to be affected by their subjective perceptions of their friends.

As noted in the introduction, participants may not be aware of the extent to which their friends play violent video games and hence used the perception of how aggressive their friends are as an anchor for estimating their friends’ amount of violent video game play. Importantly, however, the participant's aggression at Time 2 was significantly predicted by friends’ amount of violent video game play at Time 1 even when controlling for friends’ level of aggression at Time 1 (see Figure ​ Figure3). 3 ). Moreover, whereas aggression might be used for estimating violent video game exposure of the friends, participants should be well aware of the extent to which they play violent video games so that anchoring effects for participant's self‐reports are unlikely. However, given that it cannot be completely ruled out that the correlation between violent game play of friends at Time 1 and aggressive behavior of participants at Time 2 reflects a pseudocorrelation that is determined by the correlation between aggressive behavior of friends at Time 1 and aggressive behavior of the participant at Time 2, future research that employs sociocentric network analyses where information about the friends is provided by the friends themselves would be informative.

Another limitation is the employment of self‐report measures to assess aggressive behavior. Self‐report measures are quite transparent, so participants may have rated themselves more favorably than is actually warranted. In fact, mean scores of reported aggressive behavior were quite low. This reduced variance, however, typically diminishes associations with other constructs. In any case, observing how actual aggressive behavior is influenced by the social network's violent video game play would be an important endeavor for future work. It also has to be acknowledged that some participants may have reported on different friends at Time 1 and Time 2. Future research would be welcome that ensures that participants consider the same friends at different time points.

Future research may also shed some further light on the psychological processes. In the present study, the violent video game players’ higher levels of aggression accounted for the relationship between their amount of violent video game play and the participants’ reported aggression. It would be interesting to examine why the players’ aggression influences the aggression level of their social network. One possibility is that witnessing increased aggression by others (who play violent video games) leads to greater acceptance of norms condoning aggression, which are known to be an antecedent of aggressive behavior (Huesmann & Guerra, 1997 ). After all, if others behave aggressively, why should one refrain from engaging in the same behavior.

Another limitation of the present work is that it was not assessed how participants and their friends play violent video games. A recent survey (Lenhart, Smith, Anderson, Duggan, & Perrin, 2015 ) showed that many video game users play video games together with their friends, either cooperatively or competitively. This is insofar noteworthy as there might be some overlap between participants’ and their friends’ violent video game play. Moreover, cooperative video games have been shown to increase prosocial tendencies (Greitemeyer, 2013 ; Greitemeyer & Cox, 2013 ; but see Verheijen, Stoltz, van den Berg, & Cillessen, 2019 ) and decrease aggression (Velez, Greitemeyer, Whitaker, Ewoldsen, & Bushman, 2016 ). In contrast, competitive video game play increases aggressive affect and behavior (e.g., Adachi & Willoughby, 2016 ). Hence, future research should examine more closely whether participants play violent video games on their own, competitively, or cooperatively. The latter may show some positive effects of video game play, both on the player and the player's friends, whereas opposing effects should be found for competitive video games.

To obtain high statistical power and thus to increase the probability to detect significant effects, data were collected via an online survey. The current sample was drawn from the MTurk population (for a review of the trend to rely on MTurk samples in social and personality psychology, see Anderson et al., 2019 ). Samples drawn from MTurk are not demographically representative of the U.S. population as a whole. For example, MTurk samples are disproportionally young and female and they are better educated but tend to be unemployed (for a review, Keith, Tay, & Harms, 2017 ). On the other hand, MTurk samples are more representative of the U.S. population than are college student samples (Paolacci & Chandler, 2014 ) and the pool of participants is geographically diverse. Moreover, MTurk participants appear to be more attentive to survey instructions than are undergraduate students (Hauser & Schwarz, 2016 ). Nevertheless, future research on the impact of violent video game play on the player's social network that employs other samples would improve the generalizability of the present findings.

In conclusion, violent video game play is not only associated with increased aggression in the player but also in the player's social network. In fact, increased aggression due to violent video game play appears to instigate further aggression in the player's social network. This study thus provides suggestive evidence that not only players of violent video games are more aggressive, but also individuals become more aggressive who do not play violent video games themselves but are connected to others who do play.

1 Participant's perceived deprivation was positively related to both violent video game exposure, r (2,502) = 0.08, p  < .001, and reported aggression, r (2,502) = 0.14, p  < .001. However, the relationship between violent video game exposure and reported aggression, r (2,502) = 0.15, p  < .001, was relatively unaffected when controlling for perceived deprivation, r (2,499) = 0.14, p  < .001.

2 Given that the measures of violent video game exposure and aggressive behavior violated the normal distribution, Spearman's ρ coefficients were also calculated. However, the pattern of finding was very similar (e.g., the crucial relationship between the participant's aggression and friends’ amount of violent video game play was 0.18 [Pearson] and 0.17 [Spearman]). All these analyses can be obtained from the author upon request.

3 When dropping friends’ amount of violent video game play from the analysis, the participant's amount of violent video game play at Time 1 still did not predict participant's aggression at Time 2, t  = 0.44, β  = −.01, 95% CI = (− 0.02, 0.01), p  = .657 (when controlling for participant's aggression at Time 1, participant sex, and age).

4 Given that violent video games primarily model physical aggression, violent video games should have a stronger effect on the player's physical aggression than on other types of aggression. In fact, the impact of the participant's amount of violent video game play at Time 1 on the participant's physical aggression at Time 2, t  = 1.49, β  = .04, 95% CI = (− 0.00, 0.02), p  = .136 (when controlling for the participant's physical aggression at Time 1), was more pronounced than the impact on the participant's relational aggression at Time 2, t  = 0.52, β  = .02, 95% CI = (− 0.01, 0.02), p  = .603 (when controlling for the participant's relational aggression at Time 1), but both effects were not significant.

Pro and Con: Violent Video Games

To access extended pro and con arguments, sources, and discussion questions about whether violent video games contribute to youth violence, go to ProCon.org .

Around 73% of American kids age 2-17 played video games in 2019, a 6% increase over 2018. Video games accounted for 17% of kids’ entertainment time and 11% of their entertainment spending. The global video game industry was worth contributing $159.3 billion in 2020, a 9.3% increase of 9.3% from 2019.

The debate over violent video games can be traced back to the 1976 release of the game Death Race. The object of the game was to run over screaming “gremlins” with a car, at which point they would turn into tombstones. Controversy erupted because the “gremlins” resembled stick-figure humans, and it was reported that the working title of the game was Pedestrian. After protestors dragged Death Race machines out of arcades and burned them in parking lots, production of the game ceased.

In 1993, public outcry following the release of violent video games Mortal Kombat and Night Trap prompted Congress to hold hearings on regulating the sale of video games. During the hearings, California Attorney General Dan Lungren testified that violent video games have “a desensitizing impact on young, impressionable minds.” Threatened with the creation of a federal regulatory commission, the video game industry voluntarily established the  Entertainment Software Rating Board  (ESRB) on Sep. 1, 1994 to create a ratings system. Based on the video game’s content, the ESRB assigns one of the following ratings: “Early Childhood,” “Everyone,” “Everyone 10+,” “Teen,” “Mature,” “Adults Only,” or “Rating Pending” (only for use in advertising for games not yet rated). In a Pew Research Center 2008 survey, 50% of boys and 14% of girls aged 12-17 listed a game with a “Mature” or “Adults Only” rating in their current top three favorite games.

An Aug. 2015 report from the American Psychological Association determined that playing violent video games is linked to increased aggression, but it did not find sufficient evidence of a link between the games and increased violence. The organization reaffirmed this position in 2020: “There is insufficient scientific evidence to support a causal link between violent video games and violent behavior… [T]he new task force report reaffirms that there is a small, reliable association between violent video game use and aggressive outcomes, such as yelling and pushing. However, these research findings are difficult to extend to more violent outcomes.” 

• Playing violent video games causes more aggression, bullying, and fighting.
• Simulating violence such as shooting guns and hand-to-hand combat in video games can cause real-life violent behavior.
• Many perpetrators of mass shootings played violent video games.
• Violent video games desensitize players to real-life violence.
• By inhabiting violent characters in video games, children are more likely to imitate the behaviors of those characters and have difficulty distinguishing reality from fantasy.
• Exposure to violent video games is linked to lower empathy and decreased kindness.
• Video games that portray violence against women lead to more harmful attitudes and sexually violent actions towards women.
• Violent video games reinforce fighting as a means of dealing with conflict by rewarding the use of violent action with increased life force, more weapons, moving on to higher levels, and more.
• The US military uses violent video games to train soldiers to kill.
• Studies have shown violent video games may cause aggression, not violence. Further, any competitive video game or activity may cause aggression.
• Violent video games are a convenient scapegoat for those who would rather not deal with the actual causes of violence in the US.
• Simple statistics do not support the claim that violent video games cause mass shootings or other violence.
• As sales of violent video games have significantly increased, violent juvenile crime rates have significantly decreased.
• Studies have shown that violent video games can have a positive effect on kindness, civic engagement, and prosocial behaviors.
• Many risk factors are associated with youth violence, but video games are not among them.
• Violent video game players know the difference between virtual violence in the context of a game and appropriate behavior in the real world.
• Violent video games provide opportunities for children to explore consequences of violent actions, develop their moral compasses and release their stress and anger (catharsis) in the game, leading to less real world aggression.
• Studies claiming a causal link between video game violence and real life violence are flawed.

The evidence that video game violence leads to real-world aggression

A 2018 meta-analysis found that there is a small increase in real-world physical aggression among adolescents and pre-teens who play violent video games. Led by Jay Hull, a social psychologist at Dartmouth College, the study team pooled data from 24 previous studies in an attempt to avoid some of the problems that have made the question of a connection between gaming and aggression controversial.

Many previous studies, according to a story in Scientific American, have been criticized by “a small but vocal cadre of researchers [who] have argued much of the work implicating video games has serious flaws in that, among other things, it measures the frequency of aggressive thoughts or language rather than physically aggressive behaviors like hitting or pushing, which have more real-world relevance.”

Hull and team limited their analysis to studies that “measured the relationship between violent video game use and overt physical aggression,” according to the Scientific American article .

The Dartmouth analysis drew on 24 studies involving more than 17,000 participants and found that “playing violent video games is associated with increases in physical aggression over time in children and teens,” according to a Dartmouth press release describing the study , which was published Oct. 1, 2018, in the Proceedings of the National Academy of Sciences .

The studies the Dartmouth team analyzed “tracked physical aggression among users of violent video games for periods ranging from three months to four years. Examples of physical aggression included incidents such as hitting someone or being sent to the school principal’s office for fighting, and were based on reports from children, parents, teachers, and peers,” according to the press release.

The study was almost immediately called in to question. In an editorial in Psychology Today , a pair of professors claim the results of the meta-analysis are not statistically significant. Hull and team wrote in the PNAS paper that, while small, the results are indeed significant. The Psychology Today editorial makes an appeal to a 2017 statement by the American Psychological Association’s media psychology and technology division “cautioning policy makers and news media to stop linking violent games to serious real-world aggression as the data is just not there to support such beliefs.”

It should be noted, however, that the 2017 statement questions the connection between “serious” aggression while the APA Resolution of 2015 , based on a review of its 2005 resolution by its own experts, found that “the link between violent video game exposure and aggressive behavior is one of the most studied and best established. Since the earlier meta-analyses, this link continues to be a reliable finding and shows good multi-method consistency across various representations of both violent video game exposure and aggressive behavior.”

While the effect sizes are small, they’ve been similar across many studies, according to the APA resolution. The problem has been the interpretation of aggression, with some writers claiming an unfounded connection between homicides, mass shootings, and other extremes of violence. The violence the APA resolution documents is more mundane and involves the kind of bullying that, while often having dire long-term consequences, is less immediately dangerous: “insults, threats, hitting, pushing, hair pulling, biting and other forms of verbal and physical aggression.”

Minor and micro-aggressions, though, do have significant health risks, especially for mental health. People of color, LGBTQ people , and women everywhere experience higher levels of depression and anger, as well as stress-related disorders, including heart disease, asthma, obesity, accelerated aging, and premature death. The costs of even minor aggression are laid at the feet of the individuals who suffer, their friends and families, and society at large as the cost of healthcare skyrockets.

Finally, it should be noted that studies looking for a connection between game violence and physical aggression are not looking at the wider context of the way we enculturate children, especially boys. As WSU’s Stacey Hust and Kathleen Rodgers have shown, you don’t have to prove a causative effect to know that immersing kids in games filled with violence and sexist tropes leads to undesirable consequences, particularly the perpetuation of interpersonal violence in intimate relationships.

No wonder, then, that when feminist media critic Anita Saarkesian launched her YouTube series, “ Tropes vs. Women in Video Games ,” she was the target of vitriol and violence. Years later she’d joke about “her first bomb threat,” but that was only after her life had been upended by the boys club that didn’t like “this woman” showing them the “grim evidence of industry-wide sexism.”

It is a widespread concern that violent video games promote aggression, reduce pro-social behaviour, increase impulsivity and interfere with cognition as well as mood in its players. Previous experimental studies have focussed on short-term effects of violent video gameplay on aggression, yet there are reasons to believe that these effects are mostly the result of priming. In contrast, the present study is the first to investigate the effects of long-term violent video gameplay using a large battery of tests spanning questionnaires, behavioural measures of aggression, sexist attitudes, empathy and interpersonal competencies, impulsivity-related constructs (such as sensation seeking, boredom proneness, risk taking, delay discounting), mental health (depressivity, anxiety) as well as executive control functions, before and after 2 months of gameplay. Our participants played the violent video game Grand Theft Auto V, the non-violent video game The Sims 3 or no game at all for 2 months on a daily basis. No significant changes were observed, neither when comparing the group playing a violent video game to a group playing a non-violent game, nor to a passive control group. Also, no effects were observed between baseline and posttest directly after the intervention, nor between baseline and a follow-up assessment 2 months after the intervention period had ended. The present results thus provide strong evidence against the frequently debated negative effects of playing violent video games in adults and will therefore help to communicate a more realistic scientific perspective on the effects of violent video gaming.

The concern that violent video games may promote aggression or reduce empathy in its players is pervasive and given the popularity of these games their psychological impact is an urgent issue for society at large. Contrary to the custom, this topic has also been passionately debated in the scientific literature. One research camp has strongly argued that violent video games increase aggression in its players [ 1 , 2 ], whereas the other camp [ 3 , 4 ] repeatedly concluded that the effects are minimal at best, if not absent. Importantly, it appears that these fundamental inconsistencies cannot be attributed to differences in research methodology since even meta-analyses, with the goal to integrate the results of all prior studies on the topic of aggression caused by video games led to disparate conclusions [ 2 , 3 ]. These meta-analyses had a strong focus on children, and one of them [ 2 ] reported a marginal age effect suggesting that children might be even more susceptible to violent video game effects.

To unravel this topic of research, we designed a randomised controlled trial on adults to draw causal conclusions on the influence of video games on aggression. At present, almost all experimental studies targeting the effects of violent video games on aggression and/or empathy focussed on the effects of short-term video gameplay. In these studies the duration for which participants were instructed to play the games ranged from 4 min to maximally 2 h (mean = 22 min, median = 15 min, when considering all experimental studies reviewed in two of the recent major meta-analyses in the field [ 3 , 5 ]) and most frequently the effects of video gaming have been tested directly after gameplay.

It has been suggested that the effects of studies focussing on consequences of short-term video gameplay (mostly conducted on college student populations) are mainly the result of priming effects, meaning that exposure to violent content increases the accessibility of aggressive thoughts and affect when participants are in the immediate situation [ 6 ]. However, above and beyond this the General Aggression Model (GAM, [ 7 ]) assumes that repeatedly primed thoughts and feelings influence the perception of ongoing events and therewith elicits aggressive behaviour as a long-term effect. We think that priming effects are interesting and worthwhile exploring, but in contrast to the notion of the GAM our reading of the literature is that priming effects are short-lived (suggested to only last for <5 min and may potentially reverse after that time [ 8 ]). Priming effects should therefore only play a role in very close temporal proximity to gameplay. Moreover, there are a multitude of studies on college students that have failed to replicate priming effects [ 9 , 10 , 11 ] and associated predictions of the so-called GAM such as a desensitisation against violent content [ 12 , 13 , 14 ] in adolescents and college students or a decrease of empathy [ 15 ] and pro-social behaviour [ 16 , 17 ] as a result of playing violent video games.

However, in our view the question that society is actually interested in is not: “Are people more aggressive after having played violent video games for a few minutes? And are these people more aggressive minutes after gameplay ended?”, but rather “What are the effects of frequent, habitual violent video game playing? And for how long do these effects persist (not in the range of minutes but rather weeks and months)?” For this reason studies are needed in which participants are trained over longer periods of time, tested after a longer delay after acute playing and tested with broader batteries assessing aggression but also other relevant domains such as empathy as well as mood and cognition. Moreover, long-term follow-up assessments are needed to demonstrate long-term effects of frequent violent video gameplay. To fill this gap, we set out to expose adult participants to two different types of video games for a period of 2 months and investigate changes in measures of various constructs of interest at least one day after the last gaming session and test them once more 2 months after the end of the gameplay intervention. In contrast to the GAM, we hypothesised no increases of aggression or decreases in pro-social behaviour even after long-term exposure to a violent video game due to our reasoning that priming effects of violent video games are short-lived and should therefore not influence measures of aggression if they are not measured directly after acute gaming. In the present study, we assessed potential changes in the following domains: behavioural as well as questionnaire measures of aggression, empathy and interpersonal competencies, impulsivity-related constructs (such as sensation seeking, boredom proneness, risk taking, delay discounting), and depressivity and anxiety as well as executive control functions. As the effects on aggression and pro-social behaviour were the core targets of the present study, we implemented multiple tests for these domains. This broad range of domains with its wide coverage and the longitudinal nature of the study design enabled us to draw more general conclusions regarding the causal effects of violent video games.

Materials and methods

Participants.

Ninety healthy participants (mean age = 28 years, SD = 7.3, range: 18–45, 48 females) were recruited by means of flyers and internet advertisements. The sample consisted of college students as well as of participants from the general community. The advertisement mentioned that we were recruiting for a longitudinal study on video gaming, but did not mention that we would offer an intervention or that we were expecting training effects. Participants were randomly assigned to the three groups ruling out self-selection effects. The sample size was based on estimates from a previous study with a similar design [ 18 ]. After complete description of the study, the participants’ informed written consent was obtained. The local ethics committee of the Charité University Clinic, Germany, approved of the study. We included participants that reported little, preferably no video game usage in the past 6 months (none of the participants ever played the game Grand Theft Auto V (GTA) or Sims 3 in any of its versions before). We excluded participants with psychological or neurological problems. The participants received financial compensation for the testing sessions (200 Euros) and performance-dependent additional payment for two behavioural tasks detailed below, but received no money for the training itself.

The violent video game group (5 participants dropped out between pre- and posttest, resulting in a group of n  = 25, mean age = 26.6 years, SD = 6.0, 14 females) played the game Grand Theft Auto V on a Playstation 3 console over a period of 8 weeks. The active control group played the non-violent video game Sims 3 on the same console (6 participants dropped out, resulting in a group of n  = 24, mean age = 25.8 years, SD = 6.8, 12 females). The passive control group (2 participants dropped out, resulting in a group of n  = 28, mean age = 30.9 years, SD = 8.4, 12 females) was not given a gaming console and had no task but underwent the same testing procedure as the two other groups. The passive control group was not aware of the fact that they were part of a control group to prevent self-training attempts. The experimenters testing the participants were blind to group membership, but we were unable to prevent participants from talking about the game during testing, which in some cases lead to an unblinding of experimental condition. Both training groups were instructed to play the game for at least 30 min a day. Participants were only reimbursed for the sessions in which they came to the lab. Our previous research suggests that the perceived fun in gaming was positively associated with training outcome [ 18 ] and we speculated that enforcing training sessions through payment would impair motivation and thus diminish the potential effect of the intervention. Participants underwent a testing session before (baseline) and after the training period of 2 months (posttest 1) as well as a follow-up testing sessions 2 months after the training period (posttest 2).

Grand Theft Auto V (GTA)

GTA is an action-adventure video game situated in a fictional highly violent game world in which players are rewarded for their use of violence as a means to advance in the game. The single-player story follows three criminals and their efforts to commit heists while under pressure from a government agency. The gameplay focuses on an open world (sandbox game) where the player can choose between different behaviours. The game also allows the player to engage in various side activities, such as action-adventure, driving, third-person shooting, occasional role-playing, stealth and racing elements. The open world design lets players freely roam around the fictional world so that gamers could in principle decide not to commit violent acts.

The Sims 3 (Sims)

Sims is a life simulation game and also classified as a sandbox game because it lacks clearly defined goals. The player creates virtual individuals called “Sims”, and customises their appearance, their personalities and places them in a home, directs their moods, satisfies their desires and accompanies them in their daily activities and by becoming part of a social network. It offers opportunities, which the player may choose to pursue or to refuse, similar as GTA but is generally considered as a pro-social and clearly non-violent game.

Assessment battery

To assess aggression and associated constructs we used the following questionnaires: Buss–Perry Aggression Questionnaire [ 19 ], State Hostility Scale [ 20 ], Updated Illinois Rape Myth Acceptance Scale [ 21 , 22 ], Moral Disengagement Scale [ 23 , 24 ], the Rosenzweig Picture Frustration Test [ 25 , 26 ] and a so-called World View Measure [ 27 ]. All of these measures have previously been used in research investigating the effects of violent video gameplay, however, the first two most prominently. Additionally, behavioural measures of aggression were used: a Word Completion Task, a Lexical Decision Task [ 28 ] and the Delay frustration task [ 29 ] (an inter-correlation matrix is depicted in Supplementary Figure 1 1). From these behavioural measures, the first two were previously used in research on the effects of violent video gameplay. To assess variables that have been related to the construct of impulsivity, we used the Brief Sensation Seeking Scale [ 30 ] and the Boredom Propensity Scale [ 31 ] as well as tasks assessing risk taking and delay discounting behaviourally, namely the Balloon Analogue Risk Task [ 32 ] and a Delay-Discounting Task [ 33 ]. To quantify pro-social behaviour, we employed: Interpersonal Reactivity Index [ 34 ] (frequently used in research on the effects of violent video gameplay), Balanced Emotional Empathy Scale [ 35 ], Reading the Mind in the Eyes test [ 36 ], Interpersonal Competence Questionnaire [ 37 ] and Richardson Conflict Response Questionnaire [ 38 ]. To assess depressivity and anxiety, which has previously been associated with intense video game playing [ 39 ], we used Beck Depression Inventory [ 40 ] and State Trait Anxiety Inventory [ 41 ]. To characterise executive control function, we used a Stop Signal Task [ 42 ], a Multi-Source Interference Task [ 43 ] and a Task Switching Task [ 44 ] which have all been previously used to assess effects of video gameplay. More details on all instruments used can be found in the Supplementary Material.

Data analysis

On the basis of the research question whether violent video game playing enhances aggression and reduces empathy, the focus of the present analysis was on time by group interactions. We conducted these interaction analyses separately, comparing the violent video game group against the active control group (GTA vs. Sims) and separately against the passive control group (GTA vs. Controls) that did not receive any intervention and separately for the potential changes during the intervention period (baseline vs. posttest 1) and to test for potential long-term changes (baseline vs. posttest 2). We employed classical frequentist statistics running a repeated-measures ANOVA controlling for the covariates sex and age.

Since we collected 52 separate outcome variables and conduced four different tests with each (GTA vs. Sims, GTA vs. Controls, crossed with baseline vs. posttest 1, baseline vs. posttest 2), we had to conduct 52 × 4 = 208 frequentist statistical tests. Setting the alpha value to 0.05 means that by pure chance about 10.4 analyses should become significant. To account for this multiple testing problem and the associated alpha inflation, we conducted a Bonferroni correction. According to Bonferroni, the critical value for the entire set of n tests is set to an alpha value of 0.05 by taking alpha/ n  = 0.00024.

Since the Bonferroni correction has sometimes been criticised as overly conservative, we conducted false discovery rate (FDR) correction [ 45 ]. FDR correction also determines adjusted p -values for each test, however, it controls only for the number of false discoveries in those tests that result in a discovery (namely a significant result).

Moreover, we tested for group differences at the baseline assessment using independent t -tests, since those may hamper the interpretation of significant interactions between group and time that we were primarily interested in.

Since the frequentist framework does not enable to evaluate whether the observed null effect of the hypothesised interaction is indicative of the absence of a relation between violent video gaming and our dependent variables, the amount of evidence in favour of the null hypothesis has been tested using a Bayesian framework. Within the Bayesian framework both the evidence in favour of the null and the alternative hypothesis are directly computed based on the observed data, giving rise to the possibility of comparing the two. We conducted Bayesian repeated-measures ANOVAs comparing the model in favour of the null and the model in favour of the alternative hypothesis resulting in a Bayes factor (BF) using Bayesian Information criteria [ 46 ]. The BF 01 suggests how much more likely the data is to occur under the null hypothesis. All analyses were performed using the JASP software package ( https://jasp-stats.org ).

Sex distribution in the present study did not differ across the groups ( χ 2 p -value > 0.414). However, due to the fact that differences between males and females have been observed in terms of aggression and empathy [ 47 ], we present analyses controlling for sex. Since our random assignment to the three groups did result in significant age differences between groups, with the passive control group being significantly older than the GTA ( t (51) = −2.10, p  = 0.041) and the Sims group ( t (50) = −2.38, p  = 0.021), we also controlled for age.

The participants in the violent video game group played on average 35 h and the non-violent video game group 32 h spread out across the 8 weeks interval (with no significant group difference p  = 0.48).

To test whether participants assigned to the violent GTA game show emotional, cognitive and behavioural changes, we present the results of repeated-measure ANOVA time x group interaction analyses separately for GTA vs. Sims and GTA vs. Controls (Tables  1 – 3 ). Moreover, we split the analyses according to the time domain into effects from baseline assessment to posttest 1 (Table  2 ) and effects from baseline assessment to posttest 2 (Table  3 ) to capture more long-lasting or evolving effects. In addition to the statistical test values, we report partial omega squared ( ω 2 ) as an effect size measure. Next to the classical frequentist statistics, we report the results of a Bayesian statistical approach, namely BF 01 , the likelihood with which the data is to occur under the null hypothesis that there is no significant time × group interaction. In Table  2 , we report the presence of significant group differences at baseline in the right most column.

Since we conducted 208 separate frequentist tests we expected 10.4 significant effects simply by chance when setting the alpha value to 0.05. In fact we found only eight significant time × group interactions (these are marked with an asterisk in Tables  2 and 3 ).

When applying a conservative Bonferroni correction, none of those tests survive the corrected threshold of p  < 0.00024. Neither does any test survive the more lenient FDR correction. The arithmetic mean of the frequentist test statistics likewise shows that on average no significant effect was found (bottom rows in Tables  2 and 3 ).

In line with the findings from a frequentist approach, the harmonic mean of the Bayesian factor BF 01 is consistently above one but not very far from one. This likewise suggests that there is very likely no interaction between group × time and therewith no detrimental effects of the violent video game GTA in the domains tested. The evidence in favour of the null hypothesis based on the Bayes factor is not massive, but clearly above 1. Some of the harmonic means are above 1.6 and constitute substantial evidence [ 48 ]. However, the harmonic mean has been criticised as unstable. Owing to the fact that the sum is dominated by occasional small terms in the likelihood, one may underestimate the actual evidence in favour of the null hypothesis [ 49 ].

To test the sensitivity of the present study to detect relevant effects we computed the effect size that we would have been able to detect. The information we used consisted of alpha error probability = 0.05, power = 0.95, our sample size, number of groups and of measurement occasions and correlation between the repeated measures at posttest 1 and posttest 2 (average r  = 0.68). According to G*Power [ 50 ], we could detect small effect sizes of f  = 0.16 (equals η 2  = 0.025 and r  = 0.16) in each separate test. When accounting for the conservative Bonferroni-corrected p -value of 0.00024, still a medium effect size of f  = 0.23 (equals η 2  = 0.05 and r  = 0.22) would have been detectable. A meta-analysis by Anderson [ 2 ] reported an average effects size of r  = 0.18 for experimental studies testing for aggressive behaviour and another by Greitmeyer [ 5 ] reported average effect sizes of r  = 0.19, 0.25 and 0.17 for effects of violent games on aggressive behaviour, cognition and affect, all of which should have been detectable at least before multiple test correction.

Within the scope of the present study we tested the potential effects of playing the violent video game GTA V for 2 months against an active control group that played the non-violent, rather pro-social life simulation game The Sims 3 and a passive control group. Participants were tested before and after the long-term intervention and at a follow-up appointment 2 months later. Although we used a comprehensive test battery consisting of questionnaires and computerised behavioural tests assessing aggression, impulsivity-related constructs, mood, anxiety, empathy, interpersonal competencies and executive control functions, we did not find relevant negative effects in response to violent video game playing. In fact, only three tests of the 208 statistical tests performed showed a significant interaction pattern that would be in line with this hypothesis. Since at least ten significant effects would be expected purely by chance, we conclude that there were no detrimental effects of violent video gameplay.

This finding stands in contrast to some experimental studies, in which short-term effects of violent video game exposure have been investigated and where increases in aggressive thoughts and affect as well as decreases in helping behaviour have been observed [ 1 ]. However, these effects of violent video gaming on aggressiveness—if present at all (see above)—seem to be rather short-lived, potentially lasting <15 min [ 8 , 51 ]. In addition, these short-term effects of video gaming are far from consistent as multiple studies fail to demonstrate or replicate them [ 16 , 17 ]. This may in part be due to problems, that are very prominent in this field of research, namely that the outcome measures of aggression and pro-social behaviour, are poorly standardised, do not easily generalise to real-life behaviour and may have lead to selective reporting of the results [ 3 ]. We tried to address these concerns by including a large set of outcome measures that were mostly inspired by previous studies demonstrating effects of short-term violent video gameplay on aggressive behaviour and thoughts, that we report exhaustively.

Since effects observed only for a few minutes after short sessions of video gaming are not representative of what society at large is actually interested in, namely how habitual violent video gameplay affects behaviour on a more long-term basis, studies employing longer training intervals are highly relevant. Two previous studies have employed longer training intervals. In an online study, participants with a broad age range (14–68 years) have been trained in a violent video game for 4 weeks [ 52 ]. In comparison to a passive control group no changes were observed, neither in aggression-related beliefs, nor in aggressive social interactions assessed by means of two questions. In a more recent study, participants played a previous version of GTA for 12 h spread across 3 weeks [ 53 ]. Participants were compared to a passive control group using the Buss–Perry aggression questionnaire, a questionnaire assessing impulsive or reactive aggression, attitude towards violence, and empathy. The authors only report a limited increase in pro-violent attitude. Unfortunately, this study only assessed posttest measures, which precludes the assessment of actual changes caused by the game intervention.

The present study goes beyond these studies by showing that 2 months of violent video gameplay does neither lead to any significant negative effects in a broad assessment battery administered directly after the intervention nor at a follow-up assessment 2 months after the intervention. The fact that we assessed multiple domains, not finding an effect in any of them, makes the present study the most comprehensive in the field. Our battery included self-report instruments on aggression (Buss–Perry aggression questionnaire, State Hostility scale, Illinois Rape Myth Acceptance scale, Moral Disengagement scale, World View Measure and Rosenzweig Picture Frustration test) as well as computer-based tests measuring aggressive behaviour such as the delay frustration task and measuring the availability of aggressive words using the word completion test and a lexical decision task. Moreover, we assessed impulse-related concepts such as sensation seeking, boredom proneness and associated behavioural measures such as the computerised Balloon analogue risk task, and delay discounting. Four scales assessing empathy and interpersonal competence scales, including the reading the mind in the eyes test revealed no effects of violent video gameplay. Neither did we find any effects on depressivity (Becks depression inventory) nor anxiety measured as a state as well as a trait. This is an important point, since several studies reported higher rates of depressivity and anxiety in populations of habitual video gamers [ 54 , 55 ]. Last but not least, our results revealed also no substantial changes in executive control tasks performance, neither in the Stop signal task, the Multi-source interference task or a Task switching task. Previous studies have shown higher performance of habitual action video gamers in executive tasks such as task switching [ 56 , 57 , 58 ] and another study suggests that training with action video games improves task performance that relates to executive functions [ 59 ], however, these associations were not confirmed by a meta-analysis in the field [ 60 ]. The absence of changes in the stop signal task fits well with previous studies that likewise revealed no difference between in habitual action video gamers and controls in terms of action inhibition [ 61 , 62 ]. Although GTA does not qualify as a classical first-person shooter as most of the previously tested action video games, it is classified as an action-adventure game and shares multiple features with those action video games previously related to increases in executive function, including the need for hand–eye coordination and fast reaction times.

Taken together, the findings of the present study show that an extensive game intervention over the course of 2 months did not reveal any specific changes in aggression, empathy, interpersonal competencies, impulsivity-related constructs, depressivity, anxiety or executive control functions; neither in comparison to an active control group that played a non-violent video game nor to a passive control group. We observed no effects when comparing a baseline and a post-training assessment, nor when focussing on more long-term effects between baseline and a follow-up interval 2 months after the participants stopped training. To our knowledge, the present study employed the most comprehensive test battery spanning a multitude of domains in which changes due to violent video games may have been expected. Therefore the present results provide strong evidence against the frequently debated negative effects of playing violent video games. This debate has mostly been informed by studies showing short-term effects of violent video games when tests were administered immediately after a short playtime of a few minutes; effects that may in large be caused by short-lived priming effects that vanish after minutes. The presented results will therefore help to communicate a more realistic scientific perspective of the real-life effects of violent video gaming. However, future research is needed to demonstrate the absence of effects of violent video gameplay in children.

Do Video Games Cause Violence: Essay Sample

Do video games cause violence: essay introduction, violence in video games essay: problem analysis, positive effect of violent video games: essay body paragraph, effects of violent video games: essay conclusion, works cited.

Video games are electronic devices that require the interaction of a user. This enables the generation of visual feedback. Video games vary from handheld devices to mainframe computers.

Video games started as early as the mid-20th century, and today their popularity has grown tremendously. The entertainment industry that produces them has grown in leaps and bounds.

Video games have both positive and negative effects on the consumers. This paper will focus on how exposure to violent video games can have major negative effects on children’s behavior in terms of education, aggressiveness, and creativity.

In recent times, the debates about aggressiveness in children due to exposure to video games have been on the rise. There is much violence in video games, and it is estimated that “over 85% of the games contain some violence and approximately half of the video games include serious violent actions” (Carnagey, Anderson and Bushman 489).

Most video games are rated E, meaning they can be sold to children of all ages starting from six years old. However, a close examination of these games shows that the parents consider them violent. This is detrimental to the youths because exposure to violence in video games has worse effects than those caused by abusive parents, coming from a broken home, or associating with antisocial peers.

Children who play violent video games have increased aggressive cognitions, aggressive behavior, psychological arousal as well as antisocial behavior. Furthermore, exposure to violence in the games leads to desensitization- “a reduction in emotion-related physiological reactivity to real violence” (Carnagey et al 490).

This means that when children are exposed to violence, they become used to it and may grow up thinking violence is the norm. For example, when children are shown a violent clip for the first time, they react with a lot of anxiety, but a second clip with similar content does not have the same effect because they have become immune to violence. This is dangerous because it lowers the children’s responsiveness to real violence.

In video games, children are exposed to violence in a positive manner, with exciting music and sounds and beautiful visual effects, which are used as rewards for violent actions in the game. This leads to reduced physiological arousal, for example, the heart rate. Eventually, desensitization occurs, and such children are less likely to notice violent acts or events or sympathize with victims of violence.

They also have a less negative attitude towards violence and generally believe the world is unsafe, which leads to the need for violence to protect oneself. Such children are less likely to seek for help in cases of violence because they have a decreased perception of injury. In addition, such children have increased aggression and are more likely to unleash violence toward other children at school.

Some children spend a considerable amount of time playing video games which impacts their school performance negatively. This is because they devote a lot of time to playing video games at the expense of schoolwork. This is especially true for children who have already had a problem with schoolwork

. They prefer to play video games instead of doing homework, especially if they keep failing. To enjoy a bit of success, they turn to video games where they can achieve victory. For example, for killing the villain in the game, they get rewarded with points, music, or sounds.

The negative effect on education is more evident among children who begin playing video games at a very young age.

These children become addicted to video games and thus ignore schoolwork. Video games also impact children’s education. Most of the time, they will be talking about their video game heroes instead of discussing useful things that might help them to improve their academics.

Some children can remember all the aspects of video games but can find it difficult to remember simple mathematical or science concepts taught in class. Some children will play video games for long periods and may fail to get enough sleep. This may lead to a lack of concentration in class the following day. Thus, they fail to grasp the content taught by teachers and jeopardize their educational growth.

The evidence is in lower grades in school exams and tests.

Still, some scholars argue that video games are good for children as they help to improve their cognitive and motor skills. This is because the “skills learned during game playing may be applied in instructional setting” (Vorderer and Bryant 336).

Video games have killed creativity in children. This is because children spend most of their time sitting in front of computers playing games. They engage in shooting, killing, and kidnapping instead of doing creative things that might help improve their cognitive skills.

They do not have an opportunity to engage with the environment or even play with their peers (Lakhanpal 1). This kind of environment allows the children to develop social skills, become inquisitive by asking questions regarding their surroundings, and learn about daily activities. On the contrary, “being glued to the video games all the time hinders this”(Lankhanpal 1).

At the same time, video games provide children with virtual worlds where they can practice skills such as leadership. These are the same skills necessary in real life. The children get a chance to learn the skills through taking roles. For instance, a child may take the part of a police officer in the game and learn a thing or two about being a police officer. This is because the games “mimic social structure” (Kiefabar 1).

Finally, it is the responsibility of parents to control how their children play video games. Too much exposure to the games has more negative effects than positive ones. Parents should therefore protect their children from the adverse effects of the games. Just as they would not allow their children to watch X-rated movies, they should also stop them from playing violent video games.

Do Violent Video Games Contribute to Youth Violence?

Around 73% of American kids age 2-17 played  video games  in 2019, a 6% increase over 2018. Video games accounted for 17% of kids’ entertainment time and 11% of their entertainment spending. The global video game industry was worth contributing $159.3 billion in 2020, a 9.3% increase of 9.3% from 2019.

Violent video games have been blamed for school shootings , increases in bullying , and violence towards women. Critics argue that these games desensitize players to violence, reward players for simulating violence, and teach children that violence is an acceptable way to resolve conflicts.

Video game advocates contend that a majority of the research on the topic is deeply flawed and that no causal relationship has been found between video games and social violence. They argue that violent video games may provide a safe outlet for aggressive and angry feelings and may reduce crime. Read more background…

Pro & Con Arguments

Pro 1 Playing violent video games causes more aggression, bullying, and fighting. 60% of middle school boys and 40% of middle school girls who played at least one Mature-rated (M-rated) game hit or beat up someone, compared with 39% of boys and 14% of girls who did not play M-rated games. [ 2 ] A peer-reviewed study in the Journal of the American Medical Association found that habitual violent video game playing had a causal link with increased, long-term, aggressive behavior. [ 63 ] Several peer-reviewed studies have shown that children who play M-rated games are more likely to bully and cyberbully their peers, get into physical fights, be hostile, argue with teachers, and show aggression towards their peers throughout the school year. [ 2 ] [ 31 ] [ 60 ] [ 61 ] [ 67 ] [ 73 ] [ 76 ] [ 80 ] Read More

Pro 2 Simulating violence such as shooting guns and hand-to-hand combat in video games can cause real-life violent behavior. Video games often require players to simulate violent actions, such as stabbing, shooting, or dismembering someone with an ax, sword, chainsaw, or other weapons. [ 23 ] Game controllers are so sophisticated and the games are so realistic that simulating the violent acts enhances the learning of those violent behaviors. [ 23 ] A peer-reviewed study found “compelling evidence that the use of realistic controllers can have a significant effect on the level of cognitive aggression.” [ 118 ] Two teenagers in Tennessee who shot at passing cars and killed one driver told police they got the idea from playing Grand Theft Auto III . [ 48 ] Bruce Bartholow, professor of psychology at the University of Missouri, spoke about the effects of simulating violence: “More than any other media, these [violent] video games encourage active participation in violence. From a psychological perspective, video games are excellent teaching tools because they reward players for engaging in certain types of behavior. Unfortunately, in many popular video games, the behavior is violence.” [ 53 ] Read More

Pro 3 Many perpetrators of mass shootings played violent video games. Kevin McCarthy, former U.S. Representative (R-CA), states: “But the idea of these video games that dehumanize individuals to have a game of shooting individuals and others – I’ve always felt that is a problem for future generations and others. We’ve watched from studies shown before of what it does to individuals. When you look at these photos of how it [mass shootings] took place, you can see the actions within video games and others.” [ 146 ] Many mass shootings have been carried out by avid video game players: Eric Harris and Dylan Klebold in the Columbine High School shooting (1999); James Holmes in the Aurora, Colorado movie theater shooting (2012); Jared Lee Loughner in the Arizona shooting that injured Rep. Gabby Giffords and killed six others (2011); and Anders Breivik, who killed 77 people in Norway (2011) and admitted to using the game Modern Warfare 2 for training. [ 43 ] [ 53 ] An FBI school shooter threat assessment stated that a student who makes threats of violence should be considered more credible if he or she also spends “inordinate amounts of time playing video games with violent themes.” [ 25 ] Dan Patrick, Republican Lieutenant Governor of Texas, stated: “We’ve always had guns, always had evil, but I see a video game industry that teaches young people to kill.” [ 145 ] Read More

Pro 4 Violent video games desensitize players to real-life violence. Desensitization to violence was defined in a Journal of Experimental Social Psychology peer-reviewed study as “a reduction in emotion-related physiological reactivity to real violence.” [ 51 ] [ 111 ] [ 112 ] The study found that just 20 minutes of playing a violent video game “can cause people to become less physiologically aroused by real violence.” People desensitized to violence are more likely to commit a violent act. [ 51 ] [ 111 ] [ 112 ] By age 18, American children will have seen 16,000 murders and 200,000 acts of violence depicted in violent video games, movies, and television. [ 110 ] A peer-reviewed study found a causal link between violent video game exposure and an increase in aggression as a result of a reduction in the brain’s response to depictions of real-life violence. [ 52 ] Studies have found reduced emotional and physiological responses to violence in both the long and short term. [ 55 ] [ 58 ] In a peer-reviewed study, violent video game exposure was linked to reduced P300 amplitudes in the brain, which is associated with desensitization to violence and increases in aggressive behavior. [ 24 ] Read More

Pro 5 By inhabiting violent characters in video games, children are more likely to imitate the behaviors of those characters and have difficulty distinguishing reality from fantasy. Violent video games require active participation and identification with violent characters, which reinforces violent behavior. Young children are more likely to confuse fantasy violence with real world violence, and without a framework for ethical decision making, they may mimic the actions they see in violent video games. [ 59 ] [ 4 ] Child Development and Early Childhood Education expert Jane Katch stated in an interview with Education Week , “I found that young children often have difficulty separating fantasy from reality when they are playing and can temporarily believe they are the character they are pretending to be.” [ 124 ] U.S. Supreme Court Justice Stephen Breyer wrote in his dissent in Brown v. ESA that “the closer a child’s behavior comes, not to watching, but to acting out horrific violence, the greater the potential psychological harm.” [ 124 ] Read More

Pro 6 Exposure to violent video games is linked to lower empathy and decreased kindness. Empathy, the ability to understand and enter into another’s feelings is believed to inhibit aggressive behavior. In a study of 150 fourth and fifth graders by Jeanne Funk, professor of psychology at the University of Toledo, violent video games were the only type of media associated with lower empathy. [ 32] A study published in the American Psychological Association’s Psychological Bulletin found that exposure to violent video games led to a lack of empathy and prosocial behavior (positive actions that benefit others). [ 65] [ 66] Eight independent tests measuring the impact of violent video games on prosocial behavior found a significant negative effect, leading to the conclusion that “exposure to violent video games is negatively correlated with helping in the real world.” [ 61] Several studies have found that children with high exposure to violent media display lower moral reasoning skills than their peers without that exposure. [ 32] [ 69] A meta-analysis of 130 international studies with over 130,000 participants concluded that violent video games “increase aggressive thoughts, angry feelings, and aggressive behaviors, and decrease empathic feelings and prosocial behaviors.” [ 123] Read More

Pro 7 Video games that portray violence against women lead to more harmful attitudes and sexually violent actions towards women. A peer-reviewed study published in the Journal of Interpersonal Violence found that video games that sexually objectify women and feature violence against women led to a statistically significant increase in rape-supportive attitudes, which are attitudes that are hostile towards rape victims. [ 68 ] Another study found that 21% of games sampled involved violence against women, while 28% portrayed them as sex objects. [ 23 ] Exposure to sexual violence in video games is linked to increases in violence towards women and false attitudes about rape, such as that women incite men to rape or that women secretly desire rape. [ 30 ] Carole Lieberman, a media psychiatrist, stated, “The more video games a person plays that have violent sexual content, the more likely one is to become desensitized to violent sexual acts and commit them.” [ 64 ] Target Australia stopped selling Grand Theft Auto V in response to customer complaints about the game’s depiction of women, which includes the option to kill a prostitute to get your money back. [ 70 ] Read More

Pro 8 Violent video games reinforce fighting as a means of dealing with conflict by rewarding the use of violent action with increased life force, more weapons, moving on to higher levels, and more. Studies suggest that when violence is rewarded in video games, players exhibit increased aggressive behavior compared to players of video games where violence is punished. [ 23 ] [ 59 ] The reward structure is one distinguishing factor between violent video games and other violent media such as movies and television shows, which do not reward viewers nor allow them to actively participate in violence. [ 23 ] [ 59 ] An analysis of 81 video games rated for teens ages 13 and up found that 73 games (90%) rewarded injuring other characters, and 56 games (69%) rewarded killing. [ 71 ] [ 72 ] People who played a video game that rewarded violence showed higher levels of aggressive behavior and aggressive cognition as compared with people who played a version of the same game that was competitive but either did not contain violence or punished violence. [ 71 ] [ 72 ] Read More

Pro 9 The US military uses violent video games to train soldiers to kill. The U.S. Marine Corps licensed Doom II in 1996 to create Marine Doom in order to train soldiers. In 2002, the U.S. Army released first-person shooter game America’s Army to recruit soldiers and prepare recruits for the battlefield. [ 6 ] While the military may benefit from training soldiers to kill using video games, kids who are exposed to these games lack the discipline and structure of the armed forces and may become more susceptible to being violent. [ 79 ] Dave Grossman, retired lieutenant colonel in the United States Army and former West Point psychology professor, stated: “[T]hrough interactive point-and-shoot video games, modern nations are indiscriminately introducing to their children the same weapons technology that major armies and law enforcement agencies around the world use to ‘turn off’ the midbrain ‘safety catch’” that prevents most people from killing. [ 77 ] Read More

Con 1 Studies have shown violent video games may cause aggression, not violence. Further, any competitive video game or activity may cause aggression. Lauren Farrar, producer for KQED Learning’s YouTube series Above the Noise , stated: “Often times after tragic mass shooting, we hear politicians turn the blame to violent video games, but the reality is that the research doesn’t really support that claim… In general, violence usually refers to physical harm or physical acts that hurt someone– like hitting, kicking, punching, and pushing. Aggression is a more broad term that refers to angry or hostile thoughts, feelings or behaviors. So everything that is violent is aggressive, but not everything that is aggressive is violent. For example, getting frustrated, yelling, talking back, arguing those are all aggressive behaviors, but they aren’t violent. The research on the effects of violent video games and behavior often looks at these milder forms of aggressive behavior.” [ 140 ] A peer-reviewed study in Psychology of Violence determined that the competitive nature of a video game was related to aggressive behavior, regardless of whether the game contained violent content. The researchers concluded: “Because past studies have failed to equate the violent and nonviolent video games on competitiveness, difficulty, and pace of action simultaneously, researchers may have attributed too much of the variability in aggression to the violent content.” [ 125 ] A follow-up study tracked high school students for four years and came to the same conclusion: the competitive nature of the games led to the increased hostile behavior. [ 126 ] Read More

Con 2 Violent video games are a convenient scapegoat for those who would rather not deal with the actual causes of violence in the US. Patrick Markey, psychology professor at Villanova University, stated: “The general story is people who play video games right after might be a little hopped up and jerky but it doesn’t fundamentally alter who they are. It is like going to see a sad movie. It might make you cry but it doesn’t make you clinically depressed… Politicians on both sides go after video games it is this weird unifying force. It makes them look like they are doing something… They [violent video games] look scary. But research just doesn’t support that there’s a link [to violent behavior].” [ 138 ] Markey also explained, “Because video games are disproportionately blamed as a culprit for mass shootings committed by White perpetrators, video game ‘blaming’ can be viewed as flagging a racial issue. This is because there is a stereotypical association between racial minorities and violent crime.” [ 141 ] Andrew Przybylski, associate professor, and director of research at the Oxford Internet Institute at Oxford University, stated: “Games have only become more realistic. The players of games and violent games have only become more diverse. And they’re played all around the world now. But the only place where you see this kind of narrative still hold any water, that games and violence are related to each other, is in the United States. [And, by blaming video games for violence,] we reduce the value of the political discourse on the topic, because we’re looking for easy answers instead of facing hard truths.” [ 139 ] Hillary Clinton, Former Secretary of State and First Lady, tweeted, “People suffer from mental illness in every other country on earth; people play video games in virtually every other country on earth. The difference is the guns.” [ 142 ] Read More

Con 3 Simple statistics do not support the claim that violent video games cause mass shootings or other violence. Katherine Newman, dean of arts and sciences at Johns Hopkins University, explained: “Millions of young people play video games full of fistfights, blazing guns, and body slams… Yet only a minuscule fraction of the consumers become violent.” [ 84 ] [ 86 ] [ 87 ] [ 91 ] [ 92 ] A report by the U.S. Secret Service and U.S. Department of Education examined 37 incidents of targeted school violence between 1974 and 2000. Of the 41 attackers studied, 27% had an interest in violent movies, 24% in violent books, and 37% exhibited interest in their own violent writings, while only 12% showed interest in violent video games. The report did not find a relationship between playing violent video games and school shootings. [ 35 ] Patrick M. Markey, director of the Interpersonal Research Laboratory at Villanova University, stated, “90% of young males play video games. Finding that a young man who committed a violent crime also played a popular video game, such as Call of Duty, Halo, or Grand Theft Auto, is as pointless as pointing out that the criminal also wore socks.” [ 84 ] Further, gun violence is less prevalent in countries with high video game use. A study of the countries representing the 10 largest video game markets internationally found no correlation between playing video games and gun-related killings. Even though US gun violence is high, the nine other countries with the highest video game usage have some of the lowest violent crime rates (and eight of those countries spend more per capita on video games than the United States). [ 97 ] Read More

Con 4 As sales of violent video games have significantly increased, violent juvenile crime rates have significantly decreased. In 2019, juvenile arrests for violent crimes were at an all-time low, a decline of 50% since 2006. Meanwhile, video game sales set a record in Mar. 2020, with Americans spending $5.6 billion on video game hardware, accessories, and assorted content. Both statistics continue a years-long trend. [ 143 ] [ 144 ] Total U.S. sales of video game hardware and software increased 204% from 1994 to 2014, reaching $13.1 billion in 2014, while violent crimes decreased 37% and murders by juveniles acting alone fell 76% in that same period. [ 82 ] [ 83 ] [ 133 ] [ 134 ] [ 135 ] The number of high school students who had been in at least one physical fight decreased from 43% in 1991 to 25% in 2013, and student reports of criminal victimization at school dropped by more than half from 1995 to 2011. [ 106 ] [ 107 ] A peer-reviewed study found that: “Monthly sales of video games were related to concurrent decreases in aggravated assaults.” [ 84 ] Read More

Con 5 Studies have shown that violent video games can have a positive effect on kindness, civic engagement, and prosocial behaviors. Research shows that playing violent video games can induce a feeling of guilt that leads to increased prosocial behavior (positive actions that benefit others) in the real world. [ 104 ] A study published in Computers in Human Behavior discovered that youths exposed to violence in action games displayed more prosocial behavior and civic engagement, “possibly due to the team-oriented multiplayer options in many of these games.” [ 103 ] Read More

Con 6 Many risk factors are associated with youth violence, but video games are not among them. The U.S. Surgeon General’s list of risk factors for youth violence included abusive parents, poverty, neglect, neighborhood crime, being male, substance use, and mental health problems, but not video games. [ 118 ] A peer-reviewed study even found a “real and significant” effect of hot weather on homicides and aggravated assaults, showing that heat is a risk factor for violence. [ 124 ] Read More

Con 7 Violent video game players know the difference between virtual violence in the context of a game and appropriate behavior in the real world. By age seven, children can distinguish fantasy from reality, and can tell the difference between video game violence and real-world violence. [ 99 ] [ 100 ] Video game players understand they are playing a game. Kids see fantasy violence all the time, from Harry Potter and the Minions to Bugs Bunny and Tom and Jerry. Their ability to distinguish between fantasy and reality prevents them from emulating video game violence in real life. [ 9 ] Exposure to fantasy is important for kids. Fisher-Price toy company stated: “Pretending is more than play: it’s a major part of a child’s development. Fantasy not only develops creative thinking, it’s also a way for children to deal with situations and problems that concern them.” [108] Read More

Con 8 Violent video games provide opportunities for children to explore consequences of violent actions, develop their moral compasses and release their stress and anger (catharsis) in the game, leading to less real world aggression. Violent games allow youth to experiment with moral issues such as war, violence, and death without real world consequences. A researcher at the Harvard Medical School Center for Mental Health and Media wrote about her research: “One unexpected theme that came up multiple times in our focus groups was a feeling among boys that violent games can teach moral lessons… Many war-themed video games allow or require players to take the roles of soldiers from different sides of a conflict, perhaps making players more aware of the costs of war.” [ 2 ] [ 38 ] A peer-reviewed study published in the Journal of Adolescent Health found that children, especially boys, play video games as a means of managing their emotions: “61.9% of boys played to ‘help me relax,’ 47.8% because ‘it helps me forget my problems,’ and 45.4% because ‘it helps me get my anger out.” [ 37 ] Researchers point to the cathartic effect of video games as a possible reason for why higher game sales have been associated with lower crime rates. [ 84 ] A peer-reviewed study in the Journal of Adolescent Research concluded that “Boys use games to experience fantasies of power and fame, to explore and master what they perceive as exciting and realistic environments (but distinct from real life), to work through angry feelings or relieve stress, and as social tools.” The games serve as a substitute for rough-and-tumble play. [ 36 ] Read More

Con 9 Studies claiming a causal link between video game violence and real life violence are flawed. Many studies failed to control for factors that contribute to children becoming violent, such as family history and mental health, plus most studies do not follow children over long periods of time. [ 10 ] [ 95 ] Video game experiments often have people playing a game for as little as ten minutes, which is not representative of how games are played in real life. In many laboratory studies, especially those involving children, researchers must use artificial measures of violence and aggression that do not translate to real-world violence and aggression, such as whether someone would force another person eat hot sauce or listen to unpleasant noises. [ 84 ] [ 94 ] According to Christopher J. Ferguson, a psychology professor at Stetson University, “matching video game conditions more carefully in experimental studies with how they are played in real life makes VVG’s [violent video games] effects on aggression essentially vanish.” [ 95 ] [ 96 ] Read More

ORIGINAL RESEARCH article

The relation of violent video games to adolescent aggression: an examination of moderated mediation effect.

• 1 Research Institute of Moral Education, College of Psychology, Nanjing Normal University, Nanjing, China
• 2 The Lab of Mental Health and Social Adaptation, Faculty of Psychology, Research Center for Mental Health Education, Southwest University, Chongqing, China

To assess the moderated mediation effect of normative beliefs about aggression and family environment on exposure to violent video games and adolescent aggression, the subjects self-reported their exposure to violent video games, family environment, normative beliefs about aggression, and aggressive behavior. The results showed that there was a significant positive correlation between exposure to violent video games and adolescent aggression; normative beliefs about aggression had a mediation effect on exposure to violent video games and adolescent aggression, while family environment moderated the first part of the mediation process. For individuals with a good family environment, exposure to violent video games had only a direct effect on aggression; however, for those with poor family environment, it had both direct and indirect effects mediated by normative beliefs about aggression. This moderated mediation model includes some notions of General Aggression Model (GAM) and Catalyst Model (CM), which helps shed light on the complex mechanism of violent video games influencing adolescent aggression.

Introduction

Violent video games and aggression.

The relationship between violent video games and adolescent aggression has become a hot issue in psychological research ( Wiegman and Schie, 1998 ; Anderson and Bushman, 2001 ; Anderson et al., 2010 ; Ferguson et al., 2012 ; Greitemeyer, 2014 ; Yang et al., 2014 ; Boxer et al., 2015 ). Based on the General Aggression Model (GAM), Anderson et al. suggested that violent video games constitute an antecedent variable of aggressive behavior, i.e., the degree of exposure to violent video games directly leads to an increase of aggression ( Anderson and Bushman, 2001 ; Bushman and Anderson, 2002 ; Anderson, 2004 ; Anderson et al., 2004 ). Related longitudinal studies ( Anderson et al., 2008 ), meta-analyses ( Anderson et al., 2010 ; Greitemeyer and Mugge, 2014 ), event-related potential studies ( Bailey et al., 2011 ; Liu et al., 2015 ), and trials about juvenile delinquents ( DeLisi et al., 2013 ) showed that exposure to violent video games significantly predicts adolescent aggression.

Although Anderson et al. insisted on using the GAM to explain the effect of violent video games on aggression, other researchers have proposed alternative points of view. For example, a meta-analysis by Sherry (2001) suggested that violent video games have minor influence on adolescent aggression. Meanwhile, Ferguson (2007) proposed that publication bias (or file drawer effect) may have implications in the effect of violent video games on adolescent aggression. Publication bias means that compared with articles with negative results, those presenting positive results (such as statistical significance) are more likely to be published ( Rosenthal and Rosnow, 1991 ). A meta-analysis by Ferguson (2007) found that after publication bias adjustment, the related studies cannot support the hypothesis that violent video games are highly correlated with aggression. Then, Ferguson et al. proposed a Catalyst Model (CM), which is opposite to the GAM. According to this model, genetic predisposition can lead to an aggressive child temperament and aggressive adult personality. Individuals who have an aggressive temperament or an aggressive personality are more likely to produce violent behavior during times of environmental strain. Environmental factors act as catalysts for violent acts for an individual who have a violence-prone personality. This means that although the environment does not cause violent behavior, but it can moderate the causal influence of biology on violence. The CM model suggested that exposure to violent video games is not an antecedent variable of aggressive behavior, but only acts as a catalyst influencing its form ( Ferguson et al., 2008 ). Much of studies ( Ferguson et al., 2009 , 2012 ; Ferguson, 2013 , 2015 ; Furuya-Kanamori and Doi, 2016 ; Huesmann et al., 2017 ) found that adolescent aggression cannot be predicted by the exposure to violent video games, but it is closely related to antisocial personality traits, peer influence, and family violence.

Anderson and his collaborators ( Groves et al., 2014 ; Kepes et al., 2017 ) suggested there were major methodological shortcomings in the studies of Ferguson et al. and redeclared the validity of their own researches. Some researchers supported Anderson et al. and criticized Ferguson’s view ( Gentile, 2015 ; Rothstein and Bushman, 2015 ). However, Markey (2015) held a neutral position that extreme views should not be taken in the relationship between violent video games and aggression.

In fact, the relation of violent video games to aggression is complicated. Besides the controversy between the above two models about whether there is an influence, other studies explored the role of internal factors such as normative belief about aggression and external factors such as family environment in the relationship between violent video games and aggression.

Normative Beliefs About Aggression, Violence Video Games, and Aggression

Normative beliefs about aggression are one of the most important cognitive factors influencing adolescent aggression; they refer to an assessment of aggression acceptability by an individual ( Huesmann and Guerra, 1997 ). They can be divided into two types: general beliefs and retaliatory beliefs. The former means a general view about aggression, while the latter reflects aggressive beliefs in provocative situations. Normative beliefs about aggression reflect the degree acceptance of aggression, which affects the choice of aggressive behavior.

Studies found that normative beliefs about aggression are directly related to aggression. First, self-reported aggression is significantly correlated to normative beliefs about aggression ( Bailey and Ostrov, 2008 ; Li et al., 2015 ). General normative beliefs about aggression can predict young people’s physical, verbal, and indirect aggression ( Lim and Ang, 2009 ); retaliatory normative beliefs about aggression can anticipate adolescent retaliation behavior after 1 year ( Werner and Hill, 2010 ; Krahe and Busching, 2014 ). There is a longitudinal temporal association of normative beliefs about aggression with aggression ( Krahe and Busching, 2014 ). Normative beliefs about aggression are significantly positively related to online aggressive behavior ( Wright and Li, 2013 ), which is the most important determining factor of adolescent cyberbullying ( Kowalski et al., 2014 ). Teenagers with high normative beliefs about aggression are more likely to become bullies and victims of traditional bullying and cyberbullying ( Burton et al., 2013 ). Finally, normative beliefs about aggression can significantly predict the support and reinforcement of bystanders in offline bullying and cyberbullying ( Machackova and Pfetsch, 2016 ).

According to Bandura’s social cognitive theory ( Bandura, 1989 ), violent video games can initiate adolescents’ observational learning. In this situation, not only can they imitate the aggressive behavior of the model but also their understanding and acceptability about aggression may change. Therefore, normative beliefs about aggression can also be a mediator between violent video games and adolescent aggression ( Duan et al., 2014 ; Anderson et al., 2017 ; Huesmann et al., 2017 ). Studies have shown that the mediating role of normative beliefs about aggression is not influenced by factors such as gender, prior aggression, and parental monitoring ( Gentile et al., 2014 ).

Family Environment, Violence Video Games, and Aggression

Family violence, parenting style, and other family factors have major effects on adolescent aggression. On the one hand, family environment can influence directly on aggression by shaping adolescents’ cognition and setting up behavioral models. Many studies have found that family violence and other negative factors are positively related to adolescent aggression ( Ferguson et al., 2009 , 2012 ; Ferguson, 2013 ), while active family environment can reduce the aggressive behavior ( Batanova and Loukas, 2014 ).

On the other hand, family environment can act on adolescent aggression together with other factors, such as exposure to violent video games. Analysis of the interaction between family conflict and media violence (including violence on TV and in video games) to adolescent aggression showed that teenagers living in higher conflict families with more media violence exposure show more aggressive behavior ( Fikkers et al., 2013 ). Parental monitoring is significantly correlated with reduced media violence exposure and a reduction in aggressive behavior 6 months later ( Gentile et al., 2014 ). Parental mediation can moderate the relationship between media violence exposure and normative beliefs about aggression, i.e., for children with less parental mediation, predictability of violent media exposure on normative beliefs about aggression is stronger ( Linder and Werner, 2012 ). Parental mediation is closely linked to decreased aggression caused by violent media ( Nathanson, 1999 ; Rasmussen, 2014 ; Padilla-Walker et al., 2016 ). Further studies have shown that the autonomy-supportive restrictive mediation of parents is related to a reduction in current aggressive behavior by decreasing media violence exposure; conversely, inconsistent restrictive mediation is associated with an increase of current aggressive behavior by enhancing media violence exposure ( Fikkers et al., 2017 ).

The Current Study

Despite GAM and CM hold opposite views on the relationship between violent video games and aggression, both of the two models imply the same idea that aggression cannot be separated from internal and external factors. While emphasizing on negative effects of violent video games on adolescents’ behavior, the GAM uses internal factors to explain the influencing mechanism, including aggressive beliefs, aggressive behavior scripts, and aggressive personality ( Bushman and Anderson, 2002 ; Anderson and Carnagey, 2014 ). Although the CM considers that there is no significant relation between violent video games and aggression, it also acknowledges the role of external factors such as violent video games and family violence. Thus, these two models seem to be contradictory, but in fact, they reveal the mechanism of aggression from different points of view. It will be more helpful to explore the effect of violent video games on aggression from the perspective of combination of internal and external factors.

Although previous studies have investigated the roles of normative beliefs about aggression and family factors in the relationship between violent video games and adolescent aggression separately, the combined effect of these two factors remains unstudied. The purpose of this study was to analyze the combined effect of normative beliefs about aggression and family environment. This can not only confirm the effects of violent video games on adolescent aggression further but also can clarify the influencing mechanism from the integration of GAM and CM to a certain extent. Based on the above, the following three hypotheses were proposed:

Hypothesis 1: There is a significant positive correlation between exposure to violent video games and adolescent aggression.

Hypothesis 2: Normative beliefs about aggression are the mediator of exposure to violent video games and adolescent aggression.

Hypothesis 3: The family environment can moderate the mediation effects of normative beliefs about aggression in exposure to violent video games and adolescent aggression; exposure to violent video games, family environment, normative beliefs about aggression, and aggression constitute a moderated mediation model.

Materials and Methods

Participants.

All subjects gave informed written consent for participation in this investigation, and their parents signed parental written informed consent. The study was reviewed and approved by the Professor Committee of School of Psychology, Nanjing Normal University, which is the committee responsible for providing ethics approvals. A total of 648 Chinese middle school students participated in this study, including 339 boys and 309 girls; 419 students were from cities and towns, and 229 from the countryside. There were 277 and 371 junior and high school students, respectively. Ages ranged from 12 to 19 years, averaging 14.73 ( SD  = 1.60).

Video Game Questionnaire (VGQ)

The Video Game Questionnaire ( Anderson and Dill, 2000) required participants to list their favorite five video games and assess their use frequencies, the degree of violent content, and the degree of violent images on a 7-point scale (1, participants seldom play video games, with no violent content or image; 7, participants often play video games with many violent contents and images). Methods for calculating the score of exposure to violent video games: (score of violent content in the game + score of violent images in the game) × use frequency/5. Chen et al. (2012) found that the Chinese version of this questionnaire had high internal consistency reliability and good content validity. The Chinese version was used in this study, and the Cronbach’s α coefficient of the questionnaire was 0.88.

Aggression Questionnaire (AQ)

There were 29 items in AQ ( Buss and Perry, 1992 ), including four dimensions: physical aggression, verbal aggression, anger, and hostility. The scale used 5-point scoring criteria (1, very incongruent with my features; 5, very congruent with my features). Scores for each item were added to obtain the dimension score, and dimension scores were summed to obtain the total score. The Chinese version of AQ had good internal consistency reliability and construct validity ( Ying and Dai, 2008 ). In this study, the Chinese version was used and its Cronbach’s α coefficient was 0.83.

Family Environment Scale (FES)

The FES ( Moos, 1990 ) includes 90 true-false questions and is divided into 10 subscales, including cohesion, expressiveness, conflict, independence, achievement-orientation, intellectual-cultural orientation, active-recreational orientation, moral-religious emphasis, organization, and control. The Chinese version of FES was revised by Fei et al. (1991) and used in this study. Three subscales closely related to aggression were selected, including cohesion, conflict, and moral-religious emphasis, with 27 items in total. The family environment score was the sum of scores of these three subscales (the conflict subscale was first inverted). The Cronbach’s α coefficient of the questionnaire was 0.75.

Normative Beliefs About Aggression Scale (NOBAGS)

There are 20 items in the NOBAGS ( Huesmann and Guerra, 1997 ), which includes retaliation (12 items) and general (8 items) aggression belief. A 4-point Likert scale is used (1, absolutely wrong; 4, absolutely right). The subjects were asked to assess the accuracy of the behavior described in each item. High score means high level of normative beliefs about aggression. The revised Chinese version of NOBAGS consists of two factors: retaliation (nine items) and general (six items) aggression belief. Its internal consistency coefficient and test-retest reliability are 0.81 and 0.79. Confirmative factor analysis showed that this version has good construct validity: χ 2  = 280.09, df  = 89, χ 2 / df  = 3.15, RMSEA = 0.07, SRMR = 0.04, NFI = 0.95, NNFI = 0.96, and CFI = 0.96 ( Shao and Wang, 2017 ). In this study, the Cronbach’s α coefficient of the Chinese version was 0.88.

Group testing was performed in randomly selected classes of six middle schools. All subjects completed the above four questionnaires.

Data Analysis

IBM SPSS Statistics 22 was used to analysis the correlations among study variables, the mediating effect of normative beliefs about aggression on the relationship between exposure to violent video games and aggression, and the moderating role of family environment in the relationship between exposure to violent video games and normative beliefs about aggression. In order to validate the moderated mediation model, Mplus 7 was also used.

Correlation Analysis Among Study Variables

In this study, self-reported questionnaires were used to collect data, and results might be influenced by common method bias. Therefore, the Harman’s single-factor test was used to assess common method bias before data analysis. The results showed that eigenvalues of 34 unrotated factors were greater than 1, and the amount of variation explained by the first factor was 10.01%, which is much less than 40% of the critical value. Accordingly, common method bias was not significant in this study.

As described in Table 1 , the degree of exposure to violent video games showed significant positive correlations to normative beliefs about aggression and aggression; family environment was negatively correlated to normative beliefs about aggression and aggression; normative beliefs about aggression were significantly and positively related to aggression. The gender difference of exposure to violent video games ( t  = 7.93, p  < 0.001) and normative beliefs about aggression ( t  = 2.74, p  < 0.01) were significant, which boys scored significantly higher than girls.

Mediating Effect Analysis

To examine the mediation effect of normative beliefs about aggression on the relationship between exposure to violent video games and aggression, gender factor was controlled firstly. Stepwise regression analysis showed that the regression of aggression to violent video games ( c  = 0.28, t  = 6.96, p  < 0.001), the regression of normative beliefs about aggression to violent video games ( a  = 0.19, t  = 4.69, p  < 0.001), and the regression of aggression to violent video games ( c ′ = 0.22, t  = 5.69, p  < 0.001) and normative beliefs about aggression ( b  = 0.31, t  = 8.25, p  < 0.001) were all significant. Thus, normative beliefs about aggression played a partial mediating role in exposure to violent video games and aggression. The mediation effect value was 0.06, accounting for 21.43% (0.06/0.28) of the total effect.

Moderated Mediation Effect Analysis

After standardizing scores of exposure to violent videogames, normative beliefs about aggression, family environment, and aggression, two interaction terms were calculated, including family environment × exposure to violent video games and family environment × normative beliefs about aggression. Regression analysis was carried out after controlling gender factor ( Table 2 ).

Table 2 . Moderated mediation effect analysis of the relationship between violent video exposure and aggression.

In the first step, a simple moderated model (Model 1) between exposure to violent video games and aggression was established. The result showed that exposure to violent video games had a significant effect on aggression ( c 1  = 0.24, t  = 6.13, p  < 0.001), while the effect of family environment × exposure to violent video games on aggression was not significant ( c 3  = 0.05, t  = −1.31, p  = 0.19), indicating that the relationship between exposure to violent video games and aggression was not moderated by family environment.

Next, a moderated model (Model 2) between exposure to violent video games and normative beliefs about aggression was established. The results showed that exposure to violent video games had a significant effect on normative beliefs about aggression ( a 1  = 0.13, t  = 3.42, p  < 0.001), and the effect of family environment × exposure to violent video games on normative beliefs about aggression was significant ( a 3  = −0.13, t  = −3.63, p  < 0.01).

In the third step, a moderated mediation model (Model 3) between exposure to violent video games and aggression was established. As shown in Table 2 , the effect of normative beliefs about aggression on aggression was significant ( b 1  = 0.24, t  = 6.15, p  < 0.001), and the effect of family environment × exposure to violent video games on normative beliefs about aggression was not significant ( b 2  = 0.02, t  = 0.40, p  = 0.69). Because both a 3 and b 1 were significant, exposure to violent video games, family environment, normative beliefs about aggression, and aggression constituted a moderated mediation model. Normative beliefs about aggression played a mediating role between exposure to violent video games and aggression, while family environment was a moderator between exposure to violent video games and normative beliefs about aggression. Mplus analysis proved that the moderated mediation model had good model fitting (χ 2 / df  = 1.54, CFI = 0.99, TLI = 0.98, RMSEA = 0.03, and SRMR = 0.01).

To further analyze the moderating effect of the family environment and exposure to violent video games on normative beliefs about aggression, the family environment was divided into the high and low groups, according to the principle of standard deviation, and a simple slope test was performed ( Figure 1 ). The results found that for individuals with high score of family environment, prediction of exposure to violent video games to normative beliefs about aggression was not significant ( b  = 0.08, SE  = 0.08, p  = 0.37). For individuals with low score of family environment, exposure to violent video games could significantly predict normative beliefs about aggression ( b  = 0.34, SE  = 0.09, p  < 0.001). Based on the overall findings, individuals with high scores of family environment showed a nonsignificant mediating effect of normative beliefs about aggression on the relation of exposure to violent video games and aggression; however, for individuals with low scores of family environment, normative beliefs about aggression played a partial mediating role in the effect of exposure to violent video games on aggression.

Main Findings and Implications

This study found a significantly positive correlation between exposure to violent video games and adolescent aggression, corroborating existing studies ( Anderson, 2004 ; Anderson et al., 2010 ; DeLisi et al., 2013 ; Greitemeyer and Mugge, 2014 ). Anderson et al. (2017) assessed teenagers in Australia, China, Germany, the United States, and other three countries and found that exposure to violent media, including television, movies, and video games, is positively related to adolescent aggression, demonstrating cross-cultural consistency; 8% of variance in aggression could be independently explained by exposure to violent media. In this study, after controlling for gender and family environment, R 2 for exposure to violent video games in predicting adolescent aggression was 0.05, indicating that 5% of variation in adolescent aggression could be explained by exposure to violent media. These consistent findings confirm the effect of exposure to violent video games on adolescent aggression and can be explained by the GAM. According to the GAM ( Bushman and Anderson, 2002 ; Anderson and Carnagey, 2014 ), violent video games can make teenagers acquire, repeat, and reinforce aggression-related knowledge structures, including aggressive beliefs and attitude, aggressive perceptual schemata, aggressive expectation schemata, aggressive behavior scripts, and aggression desensitization. Therefore, aggressive personality is promoted, increasing the possibility of aggressive behavior. The Hypothesis 1 of this study was validated and provided evidence for the GAM.

As shown above, normative beliefs about aggression had a partial mediation effect on the relationship between exposure to violent video games and aggression. Exposure to violent video games, on the one hand, can predict adolescent aggression directly; on the other hand, it had an indirect effect on adolescent aggression via normative beliefs about aggression. According to the above results, when exposure to violent video games changes by 1 standard deviation, adolescent aggression varies by 0.28 standard deviation, with 0.22 standard deviation being a direct effect of exposure to violent video games on adolescent aggression and 0.06 standard deviation representing the effect through normative beliefs about aggression. Too much violence in video games makes it easy for individuals to become accustomed to violence and emotionally apathetic towards the harmful consequences of violence. Moreover, it can make individuals accept the idea that violence is a good way of problem solving, leading to an increase in normative beliefs about aggression; under certain situational cues, it is more likely to become violent or aggressive. This conclusion is supported by other studies ( Gentile et al., 2014 ; Anderson et al., 2017 ; Huesmann et al., 2017 ). Like Hypothesis 1, Hypothesis 2 was validated the GAM.

One of the main findings of this study was the validation of Hypothesis 3: a moderated mediation model was constructed involving exposure to violent video games, family environment, normative beliefs about aggression, and aggression. Family environment moderated the first half of the mediation process of violent video games, normative beliefs about aggression, and aggression. In this study, family environment encompassed three factors, including (1) cohesion reflecting the degree of mutual commitment, assistance, and support among family members; (2) conflict reflecting the extent of anger, aggression, and conflict among family members; and (3) moral-religious emphasis reflecting the degree of emphasis on ethics, religion, and values. Individuals with high scores of family environment often help each other; seldom show anger, attack, and contradiction openly; and pay more attention to morality and values. These positive aspects would help them understand violence in video games from the right perspective, reduce recognition and acceptance of violence or aggression, and diminish the effect of violent video games on normative beliefs about aggression. Hence, exposure to violent video games could not predict normative beliefs about aggression of these individuals. By contrast, individuals with low scores of family environment are less likely to help each other; they often openly show anger, attack, and contradiction and do not pay much attention to morality and values. These negative aspects would not decrease but increase their acceptance of violence and aggression. For these individuals, because of the lack of mitigation mechanisms, exposure to violent video games could predict normative beliefs about aggression significantly.

The moderated mediation model of the relationship between exposure to violent video games and aggression could not only help reveal that exposure to violent video games can affect aggression but also provide an elaboration of the influencing mechanism. According to this model, for individuals with high scores of family environment, exposure to violent video games had only direct effect on aggression. However, for those with low scores of family environment, there was not only a direct effect of exposure to violent video games on aggression but also an indirect effect mediated by normative beliefs about aggression. In short, exposure to violence video games affecting aggression through normative beliefs about aggression is more likely to happen to adolescents with poor family environment than those with good family environment. That is, generation of adolescent aggression is not only related to internal cognitive factors but also to external situations. As Piotrowski and Valkenburg ( Piotrowski and Valkenburg, 2015 ; Valkenburg, 2015 ) pointed out, the effect of violent video games/media on adolescents is a complex interaction of dispositional, developmental, and social factors, and individual differences in susceptibility to these three factors determine the nature and the extent of this influence. The proposed model incorporated some perspectives of GAM and CM: while confirming the effect of exposure to violent video games on aggression occurrence, the combined effect of individual and environmental factors was verified.

Compared with the simple mediation or moderation model, the present moderated mediation model provided deeper insights into the internal mechanism of the effect of violent video games on aggression, providing inspirations for preventing adolescent aggression. First, in view of the close relationship between exposure to violent video games and adolescent aggression, relevant government departments should continue to improve the grading system of video games; meanwhile, parents should appropriately monitor the types of video games used by teenagers as well as the time spent and reduce the degree of exposure to violent video games. Second, by allowing teenagers to objectively distinguish between violence in games and reality, the mediating role of normative beliefs about aggression could inspire people to identify rational ways to solve violence problems and to experience the hurtful consequences of aggression. This would help adolescents change normative beliefs about aggression, establish a correct view of right and wrong, and reduce the occurrence of aggression. Finally, the moderating effect of family environment on the mediation process suggests that more attention should be paid to the important role of family environment. On the one hand, family education is closely related to adolescent aggression. Then, parents should create a good family atmosphere, publicly show anger and aggression as little as possible, and advocate and practice positive moral values. Parents should adopt authoritative styles, abandoning autocratic and indulgent parenting styles ( Casas et al., 2006 ; Sandstrom, 2007 ; Underwood et al., 2009 ; Kawabata et al., 2011 ) to minimize the negative effect of exposure to violent video games. On the other hand, for teenagers with poor family environment, while reducing exposure to violent video games, it is particularly important to change their normative beliefs about aggression, no longer viewing aggression as an alternative way to solve problems.

Limitations

Limitations of the current study should be mentioned. First, only Chinese school students were assessed, in a relatively small number, which could affect sample representativeness. A large sample of teenagers from different countries and in different ages, also including juvenile offenders, would be more accurate in revealing the effect of violent video games on adolescent aggression. Second, this study only focused on violent video games, not involving violent media such as internet and television, daily life events, wars, and other major social events. Indeed, these factors also have important effects on adolescent aggression, and their influencing mechanisms and combined effect are worth investigating further. Third, this study mainly adopted the self-report method. Use of peer, parent, or teacher reports to assess exposure to violent video games and aggression would help improve the effectiveness of the study. Fourth, there might be other mediators, moderating variables and relational models. In addition to normative beliefs about aggression and family environment, individual emotions, personality characteristics, school climate, and companions may play mediating or moderating roles in the relationship between violent video games and aggression. This study developed a moderated mediation model between family environment and normative beliefs about aggression, but the possibility of multiple mediation and mediated moderation models cannot be ruled out.

The current study showed that exposure to violent video games is positively related to adolescent aggression; normative beliefs about aggression have a mediating effect on exposure to violent video games and adolescent aggression, while the family environment regulates the first part of the mediation process. For individuals with good family environment, exposure to violent video games only has a direct effect on aggression; however, for those with poor family environment, there is an indirect effect mediated by normative beliefs about aggression alongside a direct effect. This moderated mediation model incorporates some perspectives of GAM and CM, enriching studies of generative mechanism of adolescent aggression.

Do Video Games Influence Violent Behavior?

By:  Roanna Cooper, MA and Marc Zimmerman, PhD, MI-YVPC Director

An op-ed article appeared recently in the The New York Times  discussing the Supreme Court’s decision to strike down California’s law barring the sale or rental of violent video games to people under 18.  The author, Dr. Cheryl Olson,   describes how the proposed law was based on the erroneous assumption that such games influence violent behavior in real life.

Dr. Olson suggests that the deliberately outrageous nature of violent games, though disturbing, makes them easily discernible from real life and suggests that the interactivity could potentially make such games less harmful.

She raises the question of how these two behaviors can be linked if youth violence has declined over the last several years while violent video game playing has increased significantly during the same period.

This analysis ignores the fact that such variation may be explained by factors other than the link between the two. A spurious variable–a third variable that explains the relationship between two other variables—may explain the negative correlation of video game playing and violent behavior. As one example, socioeconomic status may explain both a decline in violent behavior and an increase in video game playing. More affluent youth have the means and time to buy and play video games, which keeps them safely inside while avoiding potentially violent interactions on the street.  Dr. Olsen also cites several studies that have failed to show a connection between violent video game playing and violent behavior among youth.

This conclusion, however, may not be as clear cut as it appears.

Youth violence remains a significant public health issue

The decline of youth violence notwithstanding, it remains a significant public health issue that requires attention.Youth homicide remains the number one cause of death for African-American youth between 14 and 24 years old, and the number two cause for all children in this age group. Furthermore, the proportion of youth admitting to having committed various violent acts within the previous 12 months has remained steady or even increased somewhat in recent years ( http://pediatrics.aappublications.org/content/108/5/1222.full.pdf+html ).  Although the Columbine tragedy and others like it make the headlines, youth are killed everyday by the hands of another.  A more critical analysis of the link between video game playing and violence is necessary for fully understanding a complex problem like youth violent behavior that has many causes and correlates.

Studies support a link between violent video games and aggressive behavior

Researchers have reported experimental evidence linking violent video games to more aggressive behavior, particularly as it relates to children who are at more sensitive stages in their socialization.  These effects have been found to be particularly profound in the case of child-initiated virtual violence.

• In one study, 161 9- to 12-year olds and 354 college students were randomly assigned to play either a violent or nonviolent video game.  The participants subsequently played another computer game in which they set punishment levels to be delivered to another person participating in the study (they were not actually administered).  Information was also gathered on each participant’s recent history of violent behavior; habitual video game, television, and move habits, and several other control variables.  The authors reported three main findings: 1) participants who played one of violent video games would choose to punish their opponents with significantly more high-noise blasts than those who played the nonviolent games; 2) habitual exposure to violent media was associated with higher levels of recent violent behavior; and 3) interactive forms of media violence were more strongly related to violent behavior than exposure to non-interactive media violence.
• The second study was a cross-sectional correlational study of media habits, aggression-related individual difference variables, and aggressive behaviors of an adolescent population.  High school students (N=189) completed surveys about their violent TV, movie, and video game exposure, attitudes towards violence, and perceived norms about violent behavior and personality traits.  After statistically controlling for sex, total screen time and aggressive beliefs and attitudes, the authors found that playing violent video games predicted heightened physically aggressive behavior and violent behavior in the real world in a long-term context.
• In a third study, Anderson et al. conducted a longitudinal study of elementary school students to examine if violent video game exposure resulted in increases in aggressive behavior over time.  Surveys were given to 430 third, fourth, and fifth graders, their peers, and their teachers at two times during a school year.  The survey assessed both media habits and their attitudes about violence.  Results indicated that children who played more violent video games early in a school year changed to see the world in a more aggressive way and also changed to become more verbally and physically aggressive later in the school year.  Changes in attitude were noticed by both peers and teachers.
• Bushman and Huesmann, in a 2006 Pediatrics and Adolescent Medicine article , examined effect size estimates using meta-analysis to look at the short- and long-term effects of violent media on aggression in children and adults.  They reported a positive relationship between exposure to media violence and subsequent aggressive behavior, aggressive ideas, arousal, and anger across the studies they examined.  Consistent with the theory that long-term effects require the learning of beliefs and that young minds can easier encode new scripts via observational learning, they found that the long-term effects were greater for children.
• In a more recent review, Anderson et al. (2010) also analyzed 136 studies representing 130,296 participants from several countries.  These included experimental laboratory work, cross-sectional surveys and longitudinal studies.  Overall, they found consistent associations between playing violent video games and many measures of aggression, including self, teacher and parent reports of aggressive behavior.  Although the correlations were not high (r=0.17-0.20), they are typical for psychological studies in general and comparable with other risk factors for youth violence suggested in the 2001 Surgeon General’s Report on youth violence .

Violent video games may increase precursors to violent behavior, such as bullying

Although playing violent video games may not necessarily determine violent or aggressive behavior, it may increase precursors to violent behavior.  In fact, Dr. Olson points out that violent video games may be related to bullying, which researchers have found to be a risk factor for more serious violent behavior. Therefore, video game playing may have an indirect effect on violent behavior by increasing risk factors for it.  Doug Gentile notes that the only way for violent video games to affect serious criminal violence statistics is if they were the primary predictor of crime, which they may not be.  Rather, they represent one risk factor among many for aggression ( http://www.apa.org/monitor/2010/12/virtual-violence.aspx ).

Should video games be regulated?

L. Rowell Huesmann (2010) points out that violent video game playing may be similar to other public health threats such as exposure to cigarette smoke and led based paint .  Despite not being guaranteed, the probability of lung cancer from smoking or intelligence deficits from lead exposure is increased.  Nevertheless, we have laws controlling cigarette sales to minors and the use of lead-based paint (and other lead-based products such as gasoline) because it is a risk factor for negative health outcomes.  Huesmann argues the same analysis could be applied to video game exposure.  Although exposure to violent video games is not the sole factor contributing to aggression and violence among children and adolescents, it is a contributing risk factor that is modifiable.

Violent behavior is determined by many factors

Finally, most researchers would agree that violent behavior is determined by many factors which may combine in different ways for different youth. These factors involve neighborhoods, families, peers, and individual traits and behaviors. Researchers, for example, have found that living in a violent neighborhood and experiencing violence as a victim or witness is associated with an increased risk for violent behavior among youth. Yet, this factor alone may not cause one to be violent and most people living in such a neighborhood do not become violent perpetrators. Similarly, researchers have found consistently that exposure to family violence (e.g., spousal and child abuse, fighting and conflict) increases the risk for youth violent behavior, but does not necessarily result in violent children. Likewise, researchers have found that first person killing video game playing is associated with increased risk for violent behavior, but not all the time. Yet, constant exposure to violence from multiple sources, including first person violent video games, in the absence of positive factors that help to buffer these negative exposures is likely to increase the probability that youth will engage in violent behavior.

Despite disagreements on the exact nature of the relationship between violent video game playing and violent or aggressive behavior, significant evidence exists linking video game playing with violent behavior and its correlates.  Although we are somewhat agnostic about the role of social controls like laws banning the sale of violent video games to minors, an argument against such social controls based on the conclusion  that the video games have no effect seems to oversimplify the issue. A more in-depth and critical analysis of the issue from multiple perspectives may both help more completely understand the causes and correlates of youth violence, and provide us with some direction for creative solutions to this persistent social problem.

Violence in the media: Psychologists study potential harmful effects

Early research on the effects of viewing violence on television—especially among children—found a desensitizing effect and the potential for aggression. Is the same true for those who play violent video games?

• Video Games

Television and video violence

Virtually since the dawn of television, parents, teachers, legislators, and mental health professionals have wanted to understand the impact of television programs, particularly on children. Of special concern has been the portrayal of violence, particularly given psychologist Albert Bandura’s work in the 1970s on social learning and the tendency of children to imitate what they see.

As a result of 15 years of “consistently disturbing” findings about the violent content of children’s programs, the Surgeon General’s Scientific Advisory Committee on Television and Social Behavior was formed in 1969 to assess the impact of violence on the attitudes, values, and behavior of viewers. The resulting report and a follow-up report in 1982 by the National Institute of Mental Health identified these major effects of seeing violence on television:

• Children may become less sensitive to the pain and suffering of others.
• Children may be more fearful of the world around them.
• Children may be more likely to behave in aggressive or harmful ways toward others.

Research by psychologists L. Rowell Huesmann, Leonard Eron, and others starting in the 1980s found that children who watched many hours of violence on television when they were in elementary school tended to show higher levels of aggressive behavior when they became teenagers. By observing these participants into adulthood, Huesmann and Eron found that the ones who’d watched a lot of TV violence when they were 8 years old were more likely to be arrested and prosecuted for criminal acts as adults.

Interestingly, being aggressive as a child did not predict watching more violent TV as a teenager, suggesting that TV watching could be a cause rather than a consequence of aggressive behavior. However, later research by psychologists Douglas Gentile and Brad Bushman, among others, suggested that exposure to media violence is just one of several factors that can contribute to aggressive behavior.

Other research has found that exposure to media violence can desensitize people to violence in the real world and that, for some people, watching violence in the media becomes enjoyable and does not result in the anxious arousal that would be expected from seeing such imagery.

Video game violence

The advent of video games raised new questions about the potential impact of media violence, since the video game player is an active participant rather than merely a viewer. 97% of adolescents age 12–17 play video games—on a computer, on consoles such as the Wii, Playstation, and Xbox, or on portable devices such as Gameboys, smartphones, and tablets. A Pew Research Center survey in 2008 found that half of all teens reported playing a video game “yesterday,” and those who played every day typically did so for an hour or more.

Many of the most popular video games, such as “Call of Duty” and “Grand Theft Auto,” are violent; however, as video game technology is relatively new, there are fewer empirical studies of video game violence than other forms of media violence. Still, several meta-analytic reviews have reported negative effects of exposure to violence in video games.

A 2010 review by psychologist Craig A. Anderson and others concluded that “the evidence strongly suggests that exposure to violent video games is a causal risk factor for increased aggressive behavior, aggressive cognition, and aggressive affect and for decreased empathy and prosocial behavior.” Anderson’s earlier research showed that playing violent video games can increase a person’s aggressive thoughts, feelings, and behavior both in laboratory settings and in daily life. “One major conclusion from this and other research on violent entertainment media is that content matters,” says Anderson.

Other researchers, including psychologist Christopher J. Ferguson, have challenged the position that video game violence harms children . While his own 2009 meta-analytic review reported results similar to Anderson’s, Ferguson contends that laboratory results have not translated into real world, meaningful effects. He also claims that much of the research into video game violence has failed to control for other variables such as mental health and family life, which may have impacted the results. His work has found that children who are already at risk may be more likely to choose to play violent video games. According to Ferguson, these other risk factors, as opposed to the games, cause aggressive and violent behavior.

APA launched an analysis in 2013 of peer-reviewed research on the impact of media violence and is reviewing its policy statements in the area.

Do Video Games Inspire Violent Behavior?

Conventional wisdom suggests violent media is harming kids. But sometimes a game is just a game

By Greg Toppo

On the morning of August 12, 2013, nearly eight months after 20-year-old Adam Lanza shot his way into Sandy Hook Elementary School in Newtown, Conn., and killed 26 people, Michael Mudry, an investigator with the Connecticut State Police, drove to nearby Danbury to try to solve a little mystery. Police had found a Garmin GPS unit in Lanza's house, and its records showed that the gunman had driven to the same spot nine times in April, May and June 2012, arriving around midnight each time and staying for hours.

The GPS readout took Mudry to the vast parking lot of a suburban shopping center, about 14 miles west of Lanza's home. Workers at a movie theater there immediately recognized Lanza from a photograph. He was at the theater constantly, they told Mudry, but never to see movies. He came to the lobby to play an arcade game, the same one, over and over again, sometimes for eight to 10 hours a night. Witnesses said he would whip himself into a frenzy, and on occasion the theater manager had to unplug the game to get him to leave.

Police had been scouring Lanza's home since the shootings, and on his computer hard drive they found information on weapons magazine capacities, images of Columbine killers Eric Harris and Dylan Klebold, copies of the violent movies Bloody Wednesday and Rampage , and a list of ingredients for TNT. And like many teenaged boys, Lanza owned the typical first-person shooter, fighting and action games: Call of Duty, Dead or Alive, Grand Theft Auto.

But those weren't the games that possessed Lanza at the movie theater. The title that so consumed the Sandy Hook shooter? Dance Dance Revolution—an arcade staple that has players dance on colored squares to the rhythm of Asian techno-pop. That discovery not only surprised investigators, it also was at odds with overheated speculation in the media and around dinner tables that violent video games had helped turn Lanza into a killer.

Yet no one knows how any of these games—Dance Dance Revolution included—might have affected a kid who was clearly struggling. The truth is that decades of research have turned up no reliable causal link between playing violent video games and perpetrating actual violence. This is not to say that games have no effect. They're built to have an effect. It's just not necessarily the one that most people think.

A tradition of worry The implicit connection between violent media and violent behavior is so old that, like a barnacle clinging to a hull, it's not easily dislodged. The notion dates at least to the Victorian era, when educators, tastemakers and clergymen began criticizing what was then a fairly raucous popular culture. Violent, sex-soaked dime novels and penny-dreadful magazines were immensely popular, and upstanding publications such as Harper's and the Atlantic Monthly took delight in denouncing them. Author and critic Harold Schechter, whose 2005 book Savage Pastimes lays out a social history of violent entertainment, notes that the trend divided the literati of the time. Ralph Waldo Emerson complained about his countrymen “reading all day murders & railroad accidents,” but Nathaniel Hawthorne loved the scandal sheets so much that he had a friend ship stacks of them to Liverpool, England, while he lived abroad as a U.S. consul. The belle of Amherst herself, Emily Dickinson, relished stories of “those funny accidents where railroads meet each other, and gentlemen in factories get their heads cut off quite informally.”

The 20th century saw criticism grow more robust. In 1936 Catholic scholar John K. Ryan laid out what he called the “mental food of American children,” as seen through the media they consumed. It was a long menu, one that included “sadism, cannibalism, bestiality. Crude eroticism. Torturing, killing, kidnapping.” He was talking about daily newspaper comic strips. In 1947 critic and actor John Houseman lodged similar complaints about cartoons on television. They “run red with horrible savagery,” he wrote.

Into this fray entered Stanford University psychologist Albert Bandura, now 89, whose experimental studies in the early 1960s established the theoretical basis for limiting kids' access to violent media. In a 1961 study, Bandura and his colleagues gathered 72 preschoolers. Laboratory assistants led the kids, one at a time, into a playroom, where they sat at a small table and received instruction on how to make potato-print pictures. Soon another adult entered the room and settled into the opposite corner with a Tinkertoy set, a mallet and a five-foot, inflated Bobo clown doll, the kind that rights itself if knocked over. The adult then either quietly assembled the Tinkertoys, ignoring Bobo, or turned to the doll and began “aggressing toward it”—punching it, sitting on it, kicking it around the room, all the while saying things such as “Sock him in the nose!” and “Pow!”

After 10 minutes, each child was led into another room and invited to play with some “relatively attractive toys,” such as a fire engine, a spinning top and a doll set. But after two minutes, a lab assistant announced that these were “her very best toys” and that she'd decided to reserve them for other children. The kids were swept into a third room that held more toys, both “aggressive and nonaggressive”: a tea set, crayons, dart guns, a mallet … and a three-foot Bobo doll. You see where this is going.

Faced with the frustration of having nice new toys suddenly snatched away, the preschoolers who had watched Bobo get mistreated were more likely than the others to take out their aggression on the mini Bobo. Bandura repeated the experiment in 1963, using film and cartoon depictions of Bobo's mistreatment, with similar results. The conclusions seemed clear: watching unchecked aggression in real life, on film or in cartoons makes us more aggressive because it provides us with “social scripts” to guide our behavior. Bandura's conclusions opened a floodgate of “media effects” research that continues today.

The problem is that many of the findings, especially when applied to children's media and play, are misleading at best. Critic Gerard Jones, whose 2003 book Killing Monsters makes a case for giving kids access to “make-believe violence,” writes: “There is no evidence to suggest that punching an inflatable clown has any connection to real-life violence.” In many cases, he and others say, researchers mistake natural competitiveness or the effects of discomfort for aggression or mislabel the subjects' temporary aggression as behavior that holds the potential for violence. In an often quoted 1976 study led by Brian Coates at Washington State University, researchers found that preschoolers who watched the famously mild Mister Rogers' Neighborhood were three times more aggressive afterward. Jones suggests that the experiment itself may have made kids anxious or even angry by compelling them to “sit in a hard plastic chair in a strange room” and watch TV on cue.

It was the 1999 Columbine High School shootings that got many Americans thinking about violent video games. After the attacks, victims' families sued more than two dozen game makers, saying titles such as Doom, a first-person shooter that the two teen gunmen played, desensitized them to violence. A judge dismissed the lawsuits, but the post-Columbine uproar led more researchers to begin dissecting games, much as Bandura did for TV, in search of the roots of aggression.

Deciphering the data A few studies tried to draw distinctions between good and bad games. In a 2010 experiment, Tobias Greitemeyer, then at the University of Sussex in England, and Silvia Osswald of Ludwig Maximilian University in Germany asked subjects to play one of three video games—either a “prosocial” game, an “aggressive” game or the “neutral” game Tetris. After eight minutes, an experimenter reached for a stack of questionnaires but “accidentally” knocked a cup of pencils off the table and onto the floor. Participants who had played the prosocial game were twice as likely to help pick up the pencils as those who played the neutral or aggressive game.

Others have tried to tease out the aftereffects of playing violent games. In a 2012 study, André Melzer of the University of Luxembourg, along with Mario Gollwitzer of Philipps University Marburg in Germany, found that inexperienced players felt a need to “cleanse” themselves after playing a violent video game (the so-called Macbeth effect: “Out, damned spot!”). Researchers asked subjects to play either a driving game or the mayhem-heavy Grand Theft Auto for 15 minutes, then pick gifts from an assortment, half “hygienic” (shower gel, deodorant, toothpaste) and half nonhygienic (gummy bears, Post-it notes, a box of tea). Inexperienced players who played Grand Theft Auto were more likely to pick out hygienic products than were experienced players or inexperienced players who had played the driving game.

But neither of those studies make the case that these games lead to real-word violence. Although drawing conclusions about small population subgroups—such as kids at risk of violence—from broad population trends can be dicey, it is still worth noting that as violent video games proliferated in recent years, the number of violent youthful offenders fell—by more than half between 1994 and 2010, according to the U.S. Department of Justice. This trend is not what you would expect if these games had the power to make good boys go bad. Indeed, in a 2011 analysis of game sales from 2004 to 2008, A. Scott Cunningham of Baylor University, Benjamin Engelstätter of the Center for European Economic Research in Mannheim, Germany, and Michael R. Ward of the University of Texas at Arlington found that higher rates of violent game sales actually coincided with a drop in crimes, especially violent crimes. They concluded that any negative behavioral effects playing violent games might have are more than offset because violent people are drawn to such games, and the more they play, the less time they have for crime.

Even if violent video games are not turning people into killers, we might still wonder if they are harming our kids in subtler ways. As psychologist Douglas A. Gentile of Iowa State University puts it, whatever we practice repeatedly affects the brain. If we practice aggressive ways of thinking, feeling and reacting, he writes, “then we will get better at those.” In a 2008 survey on the gaming habits of about 2,500 young people, Gentile and his father, psychologist J. Ronald Gentile, found that children and adolescents who played more violent games were likelier to report “aggressive cognitions and behaviors.” They concluded that violent video games “appear to be exemplary teachers of aggression.” They also found that eighth and ninth graders who played violent games more frequently displayed greater “hostile attribution bias” (being vigilant for enemies) and got into more arguments with teachers.

The greatest worry is the impact on children who are already at risk. “Media is most powerful in our lives when it reinforces our existing values,” media scholar Henry Jenkins, now at the University of Southern California, said in a 2003 episode of Religion & Ethics Newsweekly . Indeed, Jenkins argued in an essay for PBS, a child who responds to a video game the same way he or she does to a real-world trauma could be showing symptoms of an emotional disturbance. So used in the right setting, a violent game could actually serve as a diagnostic tool.

But beyond such special circumstances, media effects research, with its Bobo dolls as markers of real-world aggression, is problematic. The fighting kids do in physical games and video games alike is just a simulation. In other words, it is play. It looks like fighting, wrote Brian Sutton-Smith, the late renowned play theorist, in his book The Ambiguity of Play , “but it is also the opposite of fighting … carried on by those who are not enemies and who do not intend to harm each other.”

In a way, we are pointing fingers at the wrong people. When we worry that a violent game is going to turn our kids into killers, aren't we the ones who can't tell fantasy from reality? Kids already know the difference.

Is Playing Violent Video Games Related to Teens' Mental Health?

New research indicates that video games are not as bad as we once feared..

Posted February 25, 2021 | Reviewed by Matt Huston

Key Points:

• Two recent studies provide insight into whether playing violent video games is related to mental health or aggression .
• Teens who had consistently played violent games for years also reported higher aggression compared to those with gaming patterns that changed over time.
• Researchers found no links between violent video game play and anxiety , depression , somatic symptoms, or ADHD after two years.

With so many kids still home this year, and an apparent increase in the number of teens and adults playing video games, it seems appropriate to re-examine the evidence on whether aggression in video games is associated with problems for adolescents or society. A special issue of Cyberpsychology, Behavior, and Social Networking published in January did just that. As a parent of three—aware of how video games can suck kids in—and a psychologist working at a social innovation lab that has been a leader in the games for health movement, I’m eager to look at studies that examine teens’ violent video game play and any effects later on in life. I asked, in the ongoing conversation about whether playing games like Fortnite makes teens more aggressive, depressed, or anxious, what do we now know?

After a few decades of research in this area, the answer is not definitive . There was a slew of studies in the early 2000s showing a link between violent video game play and aggressive behavior, and a subsequent onslaught of studies showing that the aggression was very slight and likely due to competition rather than the violent nature of the games themselves. For example, studies showed that people got just as aggressive when they lost at games like Mario Kart as when they lost a much more violent game such as Fortnite . It was likely the frustration of losing rather than the violence that caused people to act aggressively.

Looking at Mental Health and Gaming Over Time

Two studies in the January special issue add to the evidence showing that violent video games may not be as dangerous as they have been made out to be. These studies are unique because they looked at large samples of youth over long periods of time. This line of research helps us to consider whether extensive play in a real-world environment (i.e., living rooms, not labs) is associated with mental health functioning later on in the teen and young adult years.

The first study revisited the long-standing debate over whether violent video game play is associated with aggression and mental health symptoms in young adulthood. The study reported on 322 American teens, ages 10 to 13 at the outset, who were interviewed every year for 10 years. The study looked at patterns of violent video game play, and found three such patterns over time: high initial violence (those who played violent games when they were young and then reduced their play over time); moderates (those whose exposure to violent games was moderate but consistent throughout adolescence ); and low-increasers (those who started with low exposure to violent games, and then increased slightly over time). Most kids were low-increasers, and kids who started out with high depression scores were more likely to be in the high initial violence group. Only the kids in the moderates group were more likely to show aggressive behavior than the other two groups.

The researchers concluded that it was sustained violent game play over many years that was predictive of aggressive behavior, not the intensity of the violence alone or the degree of exposure for shorter periods. Importantly, none of the three exposure groups predicted either depression or anxiety, nor did any predict differences in prosocial behavior such as helping others.

The second study was even larger, following 3,000 adolescents from Singapore, and looking at whether playing violent video games was associated with mental health problems two years later. Results showed that neither violent video game play, nor video game time overall, predicted anxiety, depression, somatic symptoms, or attention deficit hyperactivity disorder after two years. Consistent with many previous studies, mental health symptoms at the beginning of the study were predictive of symptoms two years later. In short, no connection was found between video games and the mental health functioning of youth.

Taken together, these studies suggest that predispositions to mental health problems like depression and anxiety are more important to pay attention to than video game exposure, violent or not. There is also an implication that any potential effects of violent video games on aggressive behavior would tend to show up when use is prolonged—though the research did not show that gaming itself necessarily causes the aggressive behavior.

So, Should Parents Be Concerned?

These findings are helpful during a year when many kids have no doubt had unprecedented exposure to video games, some of them violent. The most current evidence is telling us that these games are not likely to make our kids more anxious, depressed, aggressive, or violent.

Do parents still need to watch our children’s screen time ? Yes, as too much video game play takes kids away from other valuable activities for their social, emotional, and creative development, such as using their imagination and making things that have not been given to them by programmers (stories, art, structures, fantasy play). Do parents need to be freaking out that our kids trying to find the "imposter" in a game will make them more likely to hit their friends when they are back together in person? Probably not.

We still need to pay attention to mental health symptoms; teens appear to be feeling the effects of the pandemic more than adults, and levels of depression and anxiety have reached unprecedented heights.

So let’s say the quiet part out loud: if they’re using video games to cope right now, it’s not the end of the world, and if they’re struggling psychologically, we should not be blaming the games. Normal elements of daily life have been reduced for teenagers during what should be their most expansive years, for what has become an increasingly large percentage of their lives. It is untenable, and even still, teens are showing us what they always do—that they are adaptive and resilient , and natural harm reduction experts.

As parents, let’s stay plugged in to what they’re going through, and think more about how games can be supportive of well-being. It’s needed now more than ever.

Introduction: Banning Violent Video Games

Violent video games should not be banned, violent video games should be banned, conclusion: why video games should not be banned.

The essay is an argumentative one; violent games should not be banned. Recently there has been an endless and fierce debate on whether or not to banned violent video games. For instance, the countries that constitute the European Union are planning to ban some of the European games. However, it is the view of the majority of video games, just like any other games, are there to educate and entertain.

Although there are strong reasons brought forth by those who want violent video games to be banned, here are reasons why we should not; increases self-esteem, reduction of pain, encourages teamwork, sharpening players’ wit, among others (Sterngold, 2006).

With regards to those in support of banning the game, they hold the view that the games continuously poison the minds of the viewers, especially young individuals.

It is worth noting that there are indeed strong points that need to be given a second thought before we rush in banning violent video games. It has been argued and even proved that when kids play such games, especially when the multiplayer type of game is available, then the children get to learn at a very early age to work as a teammate, which requires teamwork. Arguably, this is advantageous as it helps in keeping children together in times of need (Lebrilla, 2010).

For this matter, when they grow up, such individuals will be in a better position to be good team players. This concept has been currently deemed very vital in ensuring the success of an organization. Throughout the game, it is indeed tough to beat the opponent.

However, through concentration, acquisition of skills, and knowledge on how to win, which has been learned from each other, children are capable of the emerging winner. With this, they grow, knowing that to win, there is a need to have a team behind them.

As suggested by Bissell, 2008 violent video games have been thought to help, especially those with very high tempers, to release their anger by not hurting anybody. When very angry and one feels like inflicting pain on another human being or even killing others, it has been thought appropriate to transfer such anger to violent video games. When one engages in a shoot-out with an enemy in a video game, he/she might feel that the mission is accomplished.

Aside from assisting young individuals in sharpening their wits and problem-solving skills, violent video game plays a significant role in helping young individuals, even a few older members of society, to learn how to persevere. On the same line of thought, these games have made it possible for people to have well-coordinated hand and eye movements (Craig et al. 2007).

This has helped in making sure that reflex action/response is normal. The advantage of this is that it will play a significant role in keeping progressive illnesses at bay.

Another major point that is in support of violent video games is that it helps in sustaining the country’s economy. It is apparent that the industry of violent video games has played a significant role in the economic growth of the country. The export of the same product to other nations generates foreign income for the country.

Additionally, a good number of Americans derive their daily bread from the same industry(Konijn et al., 2007). For this reason, banning of violent video games will mean that the unemployment rate will go up, and the money generated from the industry will be lost. The industry generates close to 21 billion dollars annually (Jones & Ponton, 2003).

Additionally, doctors have proved that despite violent games being useful; in releasing anger, it is also helpful in helping a patient reduce pain. The current efforts hospitals show this making to install such games. More importantly, the games help entertain the plays as well as the viewers.

Just like when people feel entertained by watching a football match, violent game provide the same to the affected party. Considering the fact that slightly over 70.0% of American teens play these games, if it is banned, then they will indulge in even more risky activities in their quest to be entertained, for instance, drug abuse (Goldstein, 1998).

It would not be rational if the argument that supports the banning of violent games were not brought to light. It has been brought into the violent limelight game that pollutes the minds of American children.

When young individual engages too much in these games, they are addicted. The result is that they will grow up and may put into practice what they saw. A recent incident where a student walked into an institution of learning and started shooting at others, killing them on the spot, has been linked to violent video games (Anderson & Dill, 2000).

Similarly, just like any other thing that can bring addiction, violent video games, when making a young individual addicted, can be detrimental to their quest to learn. This is because most of the time, whenever they are free will, they spend time playing such games (Ferguson, 2008).

Although it has been argued that the game fosters socialization skills, it is evident that when one plays in non-multiplayer support, they grow up being persons with poor skills to socialize.

From the review of the issue of violent games, even though the game is intense, banning it will bring more harm than good. For those who advocate for the banning, it would be rational to critically analyze the benefits of the game to individuals and even society at large. For instance, it enhances teamwork, helps reduce pain, aids in releasing anger, and improves wit and hand-eye coordination, among others.

However, the disadvantages include polluting or poisoning young individuals, and addiction eats their time hence cannot engage actively in other vital activities. This thus warrants careful consideration from relevant stakeholders such as parents and the government.
